stat cap?

what are the current ingame stat caps?

32767 is the physical limit of stats. Good luck getting it anywhere near that without hacking.

did they also lift the max 60% mele cap that was introduced last year?

Melee % isn't a stat like agi, vit, psy, str or int but afaik there is no limit beyond 100% on attack forces or dd.

The new upgrades have 70% Melee and or 70% Magic attack. They can combine in dual wield to 93% (70% main hand 23.3% off hand) melee.

You will find many of the end game upgrade users have actually wrapped (pos->neg->pos again) the melee or ranged attack force.
