Why must I pay another 1000 gems after I unlocked a Talent set (Difficult to Research within a week) just to swap between talent pages? What is the whole point of this research? Just to save about two minutes compared to a regular reset?
Gear swap and talent swap is luxury. I don't recommend researching it unless you war alot. There are more important things to research.

Bare in mind,if you didn't actually needed to spend for talent resets,it would take far far far longer than that,the best stuff takes time unfortunately,don't expect to not pay a guild coin for a weeks worth research,that isn't how it works and if they did put this in there'd be many complaints for them to deal with,just leave war talents on and go full on and then farming when you chill, the less you change them the less they cost at the end of the month lol but don't hurt yourself doing that too much
My guess it was intended to be free once researched/tomed, then they realized it was too powerful and cut it back. It's a great talent but the combined cost of research/tomes/swaps is very high for what it does.
