This is just an observation and typical discussion amongst my guild mates...
The pricing on the armor cosmetics is stupid high. At the current price point, I'd be willing to pick a cosmetic armor for a single char that I play the most. If the price were lowered to say...100 TP, I would put it on most of my 12 char and even switch out armor kits if I felt like being different for the week/month. All my guild mates agree with this concept. I'm a VIP, and I don't make enough money to spend real cash on TP to buy frivolous items...so the 500/mo points I get I use for stuff like TR's and XP pots (when on sale). Even some of my richer guildies don't spend that kind of points on cosmetics due to the high price. Turbine, the cosmetics are JUST pixels...they dont make the char. better nor do they break the game so why be so greedy? If you want to be greedy, do the math on someone like me, with this example:
350 x1
OR
100 x12 (or more based on new skins or new armor acquired)
The math adds up in favor of Turbine if the cosmetic items are priced for a purchase without thought.
Maybe my guildies and I are crazy, but it seems perfectly logical to us!
EDIT: ...and as of today, I've still not purchased a SINGLE cosmetic item due to the unfair pricing.
