I don't know about you guys' math and damage math but what grind me a bit is cooldown of rogue skills compared to other "classes".
I'm gonna use my 2 lone wolves as an example.
Scoundrel level 5
Expert Marskman level 3
5 level in water, earth and fire magic
Cloak and Dagger- 6AP to use, 10 turn cooldown vs Tactical Retreat- 4AP, 9 turn cooldown
Charming Touch- 3m range, 6AP, 16(!) turn cooldown vs Rapture- 15m(!), 5AP, 6(!) turn cooldown.
Fast Track- selftarget only, 4AP, 18(!)turn cooldown vs Wildfire (any target) 6AP, 1 (!) turn cooldown.
Eye Gouge- 2.4m range, 4AP, 10 turn cooldown vs Blind- 15m range, 4AP, 1(!) turn cooldown.
Trip- single target, 3m range, 4AP, 10 turn cooldown vs Boulder Bash- AoE, 6AP, 15m range, 1 turn cooldown (!) and way higher damage.
Do you see the problem? Scoundrel skills don't scale that well, be it with level or DEX. Why even use Charming Touch over Rapture when the latter is superior apart from the fact that it does no damage and they use different saving throws?
My wizard has 1 turn cooldown on Immolation, a 13 level skill, while my rogue still has 10, 10 and 12 cooldowns on her starting skills.
Unfortunately, rogue skills were added late in the beta and probably need to be balanced more.
Finding anything in this game that has low AP cost is going to be overpowered. For wizards its late game with huge INT. For rogue its all game with normal attacks. The devs may change it or the community may mod it.
