One common complaint is that the PPT on small ships makes them unviable in later game battles: once they start ticking down they will malfunction and die, and even if you retreat them they are going to suck down a cruiser's worth of supplies! However, boosting frigate PPT across the board severely conflicts with one of the design goals of PPT: to stop a lone frigate (or several) from endlessly kiting a larger ship, a situation which leads to tedious and/or frustrating gameplay.
My proposed solution is to make it so that small ship PPT can be extended, but only when the kiting situation cannot happen: when that ship is on an escort assignment to a larger vessel.
The rule: A ship escorting a ship of a larger size class will not tick down PPT unless the ship it is escorting has an equal or lower PPT remaining. The PPT of the smaller ship effectively is "locked" to the larger ship. Letting it off its leash (for kiting) or destroying the larger ship will immediately cause PPT to start ticking down. Ships in phase, and ships with SO, cannot benefit from this rule.
Example 1: A Lasher (240 PPT) is deployed escorting an Enforcer (420 PPT). Until the Enforcer hits 240 PPT remaining, the Lasher's PPT does not tick down. After 300 seconds, both ships are at 120 PPT, assuming significant threats.
Example 2: A Lasher (240 PPT) is deployed not escorting an Enforcer (420 PPT). After 200 seconds of engaging the enemy, the Lasher is nearly out of PPT (40 remaining) while the Enforcer still has plenty (220). The player/AI assigns the Lasher as an escort in order to preserve its usefulness and save supplies, at least until 180 seconds later, when both will be at 40 and the ticking for the Lasher will start again.
Example 3: A Lasher (240 PPT) is deployed escorting an Enforcer (420 PPT). After 120 seconds of battle, the enemy has had their numbers diminished, and the player decides to remove the Escort order so the Lasher (240 PPT remaining) can flank independently of the Enforcer (300 PPT remaining). They can do this without fear of the Lasher suddenly sucking down a huge number of supplies.
Some beneficial properties I think will emerge from this mechanic:
- More balanced fleet composition by extending the usefulness of smaller ship classes.
- Allows the use of small ships in an escort role in long battles, promoting the worth of those ships. Some ships (Omen, Brawler, Vigilance, Monitor, Enforcer) really are good escorts, but that role is punished by the PPT disparity between themselves and their escortee.
- Letting escorts "off the leash" (with a full assault or similar for example) becomes a more consequential decision, as the ships will then tick down at a normal rate.
- Greater value of command points in general, as they can be used to control the flow of PPT.
- Greater value of hardened subsystems on larger ships, as they will be giving that PPT to smaller ships, while making the hullmod no longer mandatory for frigates... as long as they are escorting.
One possible downside of this proposed rule change: it encourages "escort balls", which may be a more tedious form of gameplay. However, escorting with the wrong ship, or over escorting in general, is detrimental to performance: fragile ships tend to just go 'pop!' when leashed with an escort, and escorts typically do not flank or form a good battle line. Which ships to escort and when is then a real tradeoff instead of a required choice.
This would require a change to the admiral AI in order to implement: it would need to be made aware of the value of escorting to preserve CR/PPT: when a small ship runs out of PPT, it should be assigned to escort a larger one if practical and points are available, and at the start of battles the AI should use escort order to prolong small ship liftetime. However, the AI already uses escort orders quite a bit, so I don't think this would change gameplay too much from the player perspective (other than enemy escorts not dropping dead in long fights without the intervention of high velocity ordinance).
Alternate, more complicated rule that preserves long PPT value as an independent stat:
Spoiler
The rule is simple: Modify the Escort command, such that if a ship is escorting a ship n size classes larger, PPT consumption (and CR tick down rate) is reduced by 1/(5-n). This works out to a PPT extension of (5-n)/(4-n). This could either be an intrinsic property of the escort command, or it could be a hullmod of the larger ship, a skill, etc. Put another way: Frigates escorting destroyers, cruisers, and capitals receive a bonus of 1.33, 1.5, and 2.0 to their operational times, respectively. Destroyers escorting cruisers/capitals get 1.33/1.5, and cruisers escorting capitals get 1.33.
