I like the idea of getting the Guardian, as long as the missile recovery special is removed of course and probably reduce OP while at it.
It seems kinda like the low tech counterpart to the Paragon. They both have ATC and Flux cap is the same though P has 1/4 more dissipation (that just seems to be there to counter the high shield upkeep anyway). Armour and hull are similar, P has 1.5k armour and G has 1.7k.
Though they differ a lot with shields, 0.6 efficiency, 360* omni shield with fortress vs 1 efficiency, 200* front shield.
And speed too though the difference isn't as huge, P with 30 vs G with 40 and plasma jets.
Then weapons, P has 4 big Eng, 4 med Eng and 2 med Uni vs 2 big Mis/Bal, 3 big Eng/Bal, 6 med Eng/Bal, 2 med Mis and both have other smalls.
So G has 1 more large mount and 2 more medium mounts (but 5 less smalls if you care) but if you bring G's OP down to match that doesn't matter too much.
However most of the mounts on G face forward unlike P who's are on turrets which combined with 360* shield make it much more reliable using those mounts.
On the other hand, G has more variety in it's weapons, able to have a large weapon of every type rather than just energy which doesn't have much variety anyway. Ballistics has kenetic and HE close and long range options, then missiles provide powerful strike capability allowing much more optimised builds.
Overall, after giving it the obvious nerf and maybe lowering OP, the Guardian actually looks reasonable compared to the Paragon but more dependent on good loadout and piloting.
Also I noticed that on the wiki, the Guardian has missile auto forge under hullmods though its a ship system??? Don't know what's going on there but it should be removed as well. Extended missile racks and character missile skill will give enough missiles.
Edit: Damn, I just read the other replies and what's with all the hostility. The weirdest part is that the main issue seems to be the regenerating missiles but right in the initial post it said suggested getting rid of that. As for the mention of kiting, it has to face forwards to shoot so it can't really use plasma jets effectively making it just 40 speed, the only thing it could kite is the Paragon.
If anyone still thinks it's over powered, just go to wiki and compare Guardian vs Radiant.
