I can’t speak for everyone, but I know from watching trends in other games that support microtransactions and from my own personal opinion that templates work awesome.
Look at the success of the greatsaw skin for example. That thing is amazing, and holds a price that almost compares to precursors!
While it isn’t a big deal to me since I have mine, perhaps templates for the racial armors on the TP for cash. You know, stuff like that which is cool to spend money on, can be used in combat (I hate you cool town clothes!) and gives absolutely no gameplay advantage.
Just my 2c, but also just saying people like me spend way too much real money on that cosmetic stuff, so in the immortal words of Fry – “shut up and take my money!”
