i like ur post
But remember
Most of Us veterans create a lot of toons, and they need gear in PvP to perform. I had 14 L65 with bis PvP gear. Even with the legacy armor u still have to farm an x amount of Uc's via PvP to complete a toon and if u have different purples in your miror classes well....this system locks ur gameplay per toon, we are Forced to play and x amount of time per toon to get gear and pray for RNG to get a purplefirst and second if got lucky that is not a dupe.
And if u want tank/dps gear or heal/dps gear for only 1 mirror class...yes, it's just 2 much time
It's not flexible at all as we were used at 4.0
When u talk about bolster u are somehow right, but remember gear in pvp should not be the key, Just Skill and wins. And of course having the chance to min/max so u can use your toon as if fits to your gamestyle.
if 242 is Bis, setting bolster in 236 would help a lot, specially new and returnig players (and this game needs tons of them)
BoL UC's
Higher return in GCXP for completed instances (PVP/PVE)
