I've been playing with max level set to 20 since the first RC because 15 is out of the question, I think that should be the default max level for the current amount of skills.
I'm not entirely opposed to the wrapping around, I think it'll be bearable enough with max level set to 20 and/or reducing the number of tiers (3-3-2-2?).
Combat skills are great! Nothing else to say.
L1L is absolutely useless.
L4R could use a little bonus, like reducing officer salaries by 10%?
I wholeheartedly agree with your decision to add a non-colony bonus to L5L.
T4R might need a bit of a buff since it's a specialist skill, maybe 40 max points?
T5R, nothing more needs to be said about increasing the maximum amount of points. If you're not going to do that, at least please make integrated cores not count towards the max.
Since T2L's ECM bonus is going to be moved to Elite, can the upcoming 10% ECM limit be raised to 15%?
I5L is okay on an Admin but not worth a skillpoint for the player. Maybe another bonus or buff?
I agree with other players that acquiring story points lategame could be improved.
