As a topic starter I'd like to thank devs for toning down manashield to 1.5:1
This is a good step forward ,although I think that given the overall PVP damage reduction in GU36 old 1:1 manashield would be best.
1.5:1 manashield still gives sorcerors over 25K of hit points, probably no class in the game is capable of delivering this much damage fast enough (as you well know sorcerors do not need a whole lot time to kill anyone now with outright resists fixed).
