Since there is no HM in Ghall and GToB they should use the NM/HM toggle buttons. With that option both PvE and PvP skill variations could be tested. Anet really needs to put more thought into their updates.
The problems at arenenet is basically equilavent to the problems at my own company.
Either they RED ENGINE GORED ENGINE GORED ENGINE GORED ENGINE GO up because of a lack of direction on the part of head office etc or soething gets shafted. In our case its loss of labour budgets so that our outlets get arse raped if they do anything slightly above normally because they have nothing spare to cope.
In arenanets case its the case of PVP getting shafted because PVE is where the money is at. Which is totally backwards because PVP is where this game shines and just like at my own place we would shine if money was spent on the right things.
