No one is saying the functionality is bugged.
In-game labels say 'Temporary Powers' when actually they don't expire, they don't disappear when exiting the zone, or logging out, there is no timer, or number of uses.
There is nothing else in-game to say they are NOT temporary.
How is someone who hasn't been staring at the changes for months supposed to know? Even the beta notes are weak at describing if a player will need to purchase each time they want them in PvP.
There are at least a handful of similar items just in the one set of changes. (game breaking? no)
Why does reporting these feel like an argument or something that has to be proven otherwise there is a Dev saying it's not true when clearly it is? That is just wrong.
