Ironweave set is extremely good for mana forged barrier or any cloth tank at level 60. However the stats could be bumped a little higher mainly the hit rating and defense. With casters needing 17% hit rating and also a defense rating of 140 it’s kind of hard to hit these goals having to focus so hard on the stats.
I know you guys have made your own set bonuses in the past and I feel like this set could use some major love. Here is an idea I have for a suggestion
2 set - increases your armor value from items by 20% and increases threat generated from all skills by 100%
4 set - when struck in combat, you have a 5% chance to gain 20% of your total mana. This can only occur once every 10 seconds.
6 set - your hit rating is increased by 25% of your intellect
8 set - your defense rating is increased by 100% of your intellect
