No, he means exactly KS. If you trinket CS you're so nub that you shouldn't even be allowed to reach lv80.
The point is perfectly clear for me: if you waste your trinket on KS, then you'll just eat the incoming Blind. Which is what EVERY decent rogue will do, period.
I seriously wonder, has any of you guys played some decent arenas before? Saved for a couple expetions, the majority of comments seem to deliberately ignore some of the most common rogue tactics you meet in any decent played arena match.
If your standard is the "omfg i r deepeesss i r nuking u down lolz" type rogue, no wonders people find it that trivial to win. Personally I know a lot of rogues that could beat the crap out of 90% of the tactics mentioned here
To OP: just remember one thing, even if it seems easy just get away with this. PvP never was and never will be balanced for 1v1. A all-cooldowns-ready rogue with at least a decent skill is almost unbeatable 1v1 versus the majority of classes. But don't forget that when arena hits, you'll have someone backing you up.
