I'd be up for redesigning the LB's in general
All the lb gauge is these days is:
Tank lb to cheese a mechanic or used because you have to, to live
Healer lb to save a wipe
Or melee lb to beat enrage

There's not really much choice with it. Would be cool to see personal LB's in pve at a much lower power level than shared
PVP lb's may be the testing grounds for such a thing, who knows
