Considering many a player spent time, resources and whatnot in order to have multiple heroic STR squads capable of defeating the raid, the unleashing of Revan and his Jedi onto the Squad Arenas was a far more severe blow to the playerbase than Dark Bastila.
Unless one has very specific characters (geared and starred for that matter), with godmods equipped, all the effort of farming Traya for months would have been for nothing because her team was de facto incapable of beating pay2win RevanJedi squads.
All DBast does is, giving qualified Traya Sith teams a(nother) realistic chance to beat Revan teams on offense without having to do silly workarounds with Nest and Zaul with still very low success chances.
As someone else pointed out above, nothing holds on defense, isn't supposed to hold and never will until the end of time - that is the nature of the game. Whoever bought Revan in the hopes of having a 24hours top5 team should have known better, after (likely) having played the game for more than a year.
Fools' tears are so sweet to behold. Every time were, are and will be.
And if you still think JKRevan is your god, just you wait until the day when Darth Revan and Darth Malak hit the tables. . . .
