Not yet, i have not much experience since IIRC i only played warfare a lot in the past, until i found median / paths mod.
Old titan quest was fun with warfare since I used couple of utility skill to move around (for hunting... i only put points into LMB skill...and 1 aura)
But some of changes are from community patch, so I think they rebalanced mostly endgame stuff and prevent imba combination (zero cooldown, stack avoid etc)
If I couldve mod TQ, mostly I would:
1. Increased experience gains (I noticed some mobs give more than other despite same level), up to 50% increased. It feel very grindy and slow because i keep hoping for a level up for skill points
2. Increased base move speed (tbh, playing fastest speed now feel normal to me, but TQ was a bit clunky to hit n run though)
3. Mastery reset (I made a mastery mistake and now I feel burned
heard that it will be added in next version)
4. A method to reset NPC item (I have to restart the game couple of times to find good green item from vendor, but no money.... need 500k .... i only have 200k saved up)
5.Increased quality of drops (I got tons of rare, but stat in TQ usually boring so I just collect small rare item to sell them for gold, I think runes / charms drop quite decent but i only maybe completed couple of act1 set)
At this pace, I dunno if I want to spend time until end of legendary (3rd diffculty). Not that I hate it, but i rather completing other game in the backlog(usually 8hours~ for one game)
