To be honnest, I wondered if this mod was enough to make Rogue "good enough" in order to avoid to release a PoE1 Balance Mod myself (as I did for PoE2, but in much less ambitious fashion since modding PoE1 is way less convenient).
Take into account that I just plan adjusting values, not adding a "new" effects since modding PoE1 is quite complex.
Basically, the change I have listed for Rogue (most important in bold):
Sneak Attack : add +10% per 3 lvl beyond 1, up to 50+50=100% damages at lvl 16 (ensures Rogue S tier single target damage dealer)
Dirty Fighting : 10%->15% crit (vicious fighting still +10% ; abilities are supposed to be worth more than talents, as for Fighter's Weapon mastery)
Riposte : 20% on miss, 30% on graze -> 30% on miss, 30% on graze
Deep wounds add +3 scaling per 6 lvl beyond 1 up to 9 raw damages/3s tick at level 13
Finishing Blow : 2x -> 4x per Rest
Fearsome Strike : 1x -> 4x per Rest
Withering Strike : 1x -> 2x per Encounter
Feign Death : Prone 10s -> 3s, invisible 6s -> 12s (increases spike damages through backstab, sort of god mode but still costs 3s of unability to act. It is meant to be Rogue strongest ability, their unique trait and trump card, in a similar fashion as Sacred Immolation or Twinned Arrows)
I don't plan to buff every meh ability of the game, or nerf some beloved OP abilities (Dragon Trashed is a classic 😉 ) but only to balance Class and Races. Rogues would get by far the most changes.
Note that one of the general principles of this balance mod would be to increase the number of per Rest casts for all non spellcasters. One of the biggest strength of casters (Wiz, Priest, Druids) is that they have a lots of casts for boss fights, making them God tier for such battles. Increasing the number of Per Rest casts of martial classes would balance this a bit. A lot of Per Rest abilities are actually quite good vs bosses (Unbending, Deprive the Unworthy, Finishing Blow), and I feel weird that they usually get 1-2 casts of them while casters get 4 casts on each Tier (not even counting mastery).
Apart for this, I plan to buff Fighter a bit, tune down a couple of Wiz/Priest spells and buff a couple of races. I will give more details on a dedicated thread.
I have no idea when I would be able to do that, but I have to get reviews while there are still a couple of experienced players on this forum.
