So a lot of people have complained that the champion system makes it much harder to change roles and play styles, switch from PvE to PvP etc. Because your gear is no longer the primary thing defining your stats. The solution is simple.
Give us a way to save champion point templates, at least 6, then make it free to switch, perhaps with a 30 min cooldown.
Tank leaves halfway through a dungeon? No problem, switch to your tank champ points template, Chuck on your armor and gtg.
Group breaks up so you decide to go PvP? No problem, grab that champ points pvp template and rock on.
Tired of pvp for today? Easy, switch to your harvesting and crafting template and pick some flowers.
This is basic stuff that should have been in the design from the start if zos really want to encourage play as you want.
