Lol, that's how PvP games work.
To find their info, the easiest thing to do would be to do as g346007_1906957 said: During a game of GW, click on a city and there is a display of players' powers there. Another quick-ish way is to look at the guildmates around you in arena.
But in short, there is no quick way to find guildmates' power from the guild menu that I know of.
Thanks, but its just a kind of request for the tynon team to make it so we can. Also being able to use the practice straight from the guild member window would be nice too.
