A plea to SE about future raids.
Please set fights up to always require two tanks. Eliminate the possibility of solo-tank methods altogether. Solo-tanking certain encounters, while duo-tanking other makes building a static near impossible.
As it currently stands, bringing two tanks for T6 and T7 is your best bet, but bringing one tank for T8 and T9 is your best bet. This means that an 8-man static must find a person that can play a tank role half of the time, and a DPS the other half. As someone who plays solely tank jobs, this is a huge issue. With most groups only needing a single tank for an entire static, finding a full-time tank spot is all but impossible.
Please SE, solidify the need for 2 tanks in future encounters.
