MR is stupid. But only as stupid as Dance of Fools.
If you don't like MR, replace it with something that exactly counters Dance of Fools.
That would still require timing, and some knowledge of the game. And those two issues would counter each other out.
Any problems that arise as a result of this are strictly the result of other imbalances that exist in the game.
Dance of fools should function as a % damage blocker vs all damage types (save for nano). A solid hit, should do half the damage (example) because it was partially evaded. The next hit might be full damage while the player regains their balance to dodge the next attack (Be it a perk or regular or special).
Mongo Rage should function the same way, as a % damage boost, rather then a complete and overwhelming guarantee alpha. An enraged atrox CAN miss his attack because he is enraged. Just give it a 59 or 65% chance to land any and all attacks, WITH bonus damage (Replacing the targets defense checks vs YOU only for the duration). It would be guaranteed damage, but not a guaranteed alpha.
Don't give it a debuff, unless you are gonna give Gumby a debuff for snapping his spine in three places while evading 1,000 bullets.
Either way, this game needs ALOT of work, and needs to be returned to a more gear dependent game play. The chance factor's introduced by Perks and Procs are the issue. Followed by the attempts to balance those issues.
Specials recharge too fast. And do too much damage. Too few checks/counters.
Perks are retarded. Cocoon, DoF, MR are all great examples.
All the little changes made to the game have been made for the wrong reasons. And usually come with so many secondary effects that it makes things worse then the issue being fixed.
I still love AO though. 8p
