The armor system is hot garbage. My opinion is no different. It won't be a year from now either.

How exactly does it suck?

1. It doesn't solve the problem of CC chains at all. In fact it makes it worse.
2. It forces a particular approach to the game by making you pile on the same type of damage.
3. It forces you to pile on the same target.
4. It makes it so going up 1 or 2 levels above you is almost always death.
5. It makes tactician REALLY suck. Not in fun ways. More like I don't have another weekend to reroll A1-4.
6. It makes a lot of builds pointless. Want to go retribution? Have fun when your enemy is a sponge.
7. I could go on but what's the point?

A better system would have been to add a tolerance meter that increases the chance of CC effects the lower it is but never 100% and never 0%. Base chance to land CC on a target at full tolerance would be 25%. Then as tolerance is reduced CC chance goes up. To 75% at 0 tolerance. Tolerance would be reduced by damage and would apply after resistances. A character with 75% physical resistance would mitigate 75 of 100 damage and that 25 damage would be applied to health. Whatever percentage of it's health that hit was would also be removed from tolerance. Then once tolerance is gone CC has a 75% chance to succeed.

That system would have fixed the problem intended to be fixed. It would not punish someone for playing hybrids and wouldn't make tactician so boring.
