The other day I was in a ToT, LFR group, and we had one shaman and no mages. Turns out the shaman didn't know what Heroism was.
I'm not saying we needed the buff to complete the fights, because we didn't and we completed the instance without heroism or time warp...but it appears that something needs to be added so that players learn these added abilities as they level up.
Used to be that you'd at least see the new abilities as they were gained because you had to go train, but that doesn't apply anymore since they're added automatically. I bet there are some people that don't even glance at their spellbooks to learn what all they are capable of and what not. Though they can go online to learn how to play their class better, they really shouldn't have to go to that extent to study up on their toon unless they really start progression raiding.
It's a problem when someone reaches endgame content -- even if it's only lfr, or heck, even endgame dailies -- and they have absolutely no idea that they have a powerful tool at their disposal.
I don't know. Maybe a semi-difficult, 10-15 min. solo scenario that serves as a sort-of gate for some endgame until you defeat the "beat me to be able to do this" boss.
While it doesn't really impact my play (I'm relatively easy-going and choose to let my job and home repairs provide my daily dose of stress), it would spare some folks some embarrassment...and possibly make them at least a slightly better player in the process.
As it stands, it's left to the community to provide that information ... but should someone really need to be telling a shaman in Throne of Thunder what Heroism is?
