I think the whole event is not too bad. Arena and Gauntlet difficulty should fit to each player's level (could be better, I know). Chance talis are easy to get (@ Muzak, do you confuse them with some other set? I sold hundreds of them as we don't really need them). Bloodlust is a bit tricky, but the biggest problem in my pov is soul protect as this buff is pretty rare (but we all have the alchemist...). Thing is to get them applied in the current Arena meta. Due to the clan thing, the common sense of helping each other has decreased significantly. 7 Gauntlet battles per clan member with sentinels is not too much I think, but one will have a very different perspective on that if you just started playing some weeks ago. Maybe these events should take player level more into account?
Because of that, I also share the opinion that it would have been a better start-off to place this event into the cosmos, not Arena & Gauntlet as these are the problematic areas in the game in terms of difficulty and influence of bugs and OP characters/talis.
