Am i correct?



Hmm. Average monster damage in hell: About 100 x 1000% = 1000 damage return. 50% of all monsters are ranged. Many have damage reduction and block chance. Average hit point = 5000. Skeletons have defense. Most are hit on average 30% of the time i assume.

All that damage is reduced to quite little, i assume.

Fortitude increases merc damage by a huge lot .. and increases his defense by a huge lot. Damage can go from 1500 to 5000 x 3 hits per second.

Even if 13 skeletons are hit once per second, 13 000 damage per second, reduced by all those factors, 3000 damage 3 times a second is much better. Increases his life leech too, which increases survivability.

Even if you use infinity which reduce enemy armor a lot, i'd say fortitude is still a much better choice.

Bramble combined with amp is epic.

All melee monsters takes huge damage even in p8.
Bosses deal double damage vs summons and takes even more damage.
