JKL Tier 7 bug - DoTs randomly appearing w/out turns taken

And I just watched a walkthrough video to make sure I'm not missing something - the guy had **bleep** mods and beat it first try - only one DoT on CLS the entire battle.  He had lower tenacity.  He had lower relic levels.  He also had 33 less speed than mine, yet he took more turns.  Either the event has recently been changed (this is RIDICULOUS if you change the difficulty of an event offering the same rewards midway through its run - though that's what you did to the CAT Proving Grounds........ constantly punishing new players until you'll finally have NO newer players).  

So, truly, something is wrong here.  If my CLS has WAY more speed, higher tenacity, and extra relic levels, better mods, etc. there is no way my runs on this tier should mean my CLS is slower and winding up with DoTs appearing every couple seconds five at a time.  I've spent a lot of time and resources to unlock JKL, and this is **bleep**.  Let's get this resolved quickly.
