These last few days have been pretty hectic. People (including me) were confused as **** about this game mechanic.
Apparently, if you max out your "debuff resistance" stat, you can suddenly counter the parry -> guardbreak "combo".
Meaning, if you get parried, you can counter the followup guardbreak attempt.
MEANING, you can not be punished on a successful parry anymore.
MEANING SPAMMING HEAVY ATTACKS AFTER MAXING OUT THIS STAT BECOMES A VIABLE STRATEGY
This is:
1. Game breaking, rewarding low level play, in a way that "mashing buttons" starts being effecting again, to an extent.
2. A complete change in a core mechanic that's been presented since you start playing the game (And also present in 1v1 and 2v2 modes, where gear is automatically disabled by default)
This is so absolutely backwards I can't even tell you, and I sincerely hope this is an un-intended bug. And if not, this needs to change, NOW.
Maybe the new patch will fix this GB issue, but I doubt it. Nothing even remotely similar was presented to us in the patch notes.
