I guess that a different play style, but for me i think of it this way. the nerf effects our damage, not our survival.
Our self healing is still as rediculous as it is but if you dont have the proc damage from the weapons to kill the healer, then whats the point of surviving? perhaps if you just want to keep them off the flag but thats a different matter.
What this nerf hurts us is the damage department, not the survival and since our damage has been nerfed from Sul, i think we do need the extra procs from different weapons to still do as much damage. For me, when i am fighting 1 v 2 3 4 or 5, the way i live is not really from the passive healing, it is from the victory ruch heal i get , and you have to land the kiling blow to get victory ruch.
i run with 20% Haste, i have the 2x bloodthirst during enrage, which is more than enough self heal in a moment of hurt and sustain+ potions + banner + leap away + necklace but all these is to sustain me to just stay alive so i kill 1 morr person to proc the victory rush.
TLDR. Currently i do run Sul + Baron because i have more than enough damage with sul procs, my opionion after the sul nerf, we might need to drop the Baron to get 2x proc weapons to cover for Sul nerf.
Just my opinion. just food for thought.
