Currently you have one T2 and one T3 pop in all abyssea areas and in Visions and Scars this isn't too bad, but with the need for Colorless Souls in Heroes areas, you have a massive bottleneck for those needing to kill them for any reason.

My suggestion is that we have 4 pops for T2s and 2 pops for T3s which will help alleiviate this bottleneck.
