Align buffs in TvT events

Is there any reason why mage buff set does not contain Acumen and Concentration? It would be fair to include them as well as fighter set contains Haste and Guidance.
What do you think?

P.S.: I also suggest to add information how, where and when to claim reward - somewhere in event dialog window text/chat message when event finished/forum description of the event. Of course, best would be to just push reward in the inventory automatically. It took me a while to notice that I need to claim it in one minute after the match ends. Just to avoid confusion.

The Acumen and Concentration missing is an oversight on our part and will be corrected.

We will expand the Event description on our web (we plan to do it anyway, once the configuration and times are final). There is a system message prompting you to get the reward, but I will extend it a little bit so that it is more clear.

EDIT: Will be fixed after next restart
