Personally, I have never said to myself, "Hey, self, wouldn't it be useful to buy a thief-acrobat with my Turbine Points?"
I have also never said, "Isn't it great that I can use Turbine Points to buy a rogue assassin in the store?"
Seriously, Turbine, if I use TP to buy a rogue, I want them to DISARM TRAPS. That's it. If they can't do that then I have wasted my money. Lots of them can't do that on elite quests at level.
Please respec them all into mechanics. That's all anyone wants when they use TP to buy a rogue anyway.
And having ANY rogue hireling who can't find and disarm traps at level is griefing the players. It would be like having cleric hirelings with 8 Wisdom who can't cast any healing spells.
Edited to add: Please respec all rogue hirelings into mechanics AND put skill boost on their hot bar. Not haste boost, SKILL BOOST. Thank you.
