More ways for PvErs to gimp their builds, especially if there is no way to respec these choices.
I'm going to guess that there will be a way to respec those choices - however, they are looking to increase the chance that somebody does something wrong and needs to "buy" that respec. They're increasing the amount of per toon items - the amount of investment in those per toon items either in grinding or in cold hard cash - thus, attempting to increase the chance that if somebody screws something up - they will be more likely to "buy" that respec.
Increase the per toon investment? Check.
Increase the per toon chance to screw up? Check.
Increase the likelihood of a player buying a respec? Check.
Heck, into that - add additional grinds requiring Dil as well as reduced Dil earnings - and it further increases the chances that a person will outright buy the Zen for a respec than they will attempt to grind it out...
