I would like to see some thought added to having a system where you can do the following
Ring 1 = 2pc Set bonus enchant
Ring 2 = 4pc Set bonus enchant
Shoulders = 6 pc Set bonus enchant.
I find the rotation to be insanely fun at the moment with Paladin and whist in P7, I have kept using some T2 and bits of T3, given the bonuses on T4, you will want to have both T4 and T3, leaving no room for T2 (assuming sims might prove me wrong who knows)
Would be a shame to lose this fast paced rotation, so i would like to see more applications for tier set customisation and increase the Bosses HP to counter our extra damage output.
Just my 2 cents
