This event is...well dead on my server. I'm pretty sure it's the same everywhere else, rather than complain more about it I thought it might be a good idea to make a post where players could suggest ideas for "fixing" it and boosting it's popularity.
Probably have to keep in mind that the rarity of the final floor drops needs to be kept as such because they don't want everyone to be able to get them (may not agree with this, but it appears to be how they want it now and I don't think they will budge from that).
To be really good at this event right now players have to abuse cheats (flee bots, tools to see through walls, tools to walk through walls) and that is just not right at all.
Things that put me off this event personally are:
Rewards being exact copies of old Nyzul gear (new armor designs would of been nice). This was one of the reasons VW was a partial success, sad to say but still it's the truth.
No save feature, at the very least I think there should be a save feature for the higher floors (if you get to 80, you should be able to save at 80, maybe make it a requirement that everyone has to have that 80 save to be able to enter there and not just 1 as it used to be).
Time limit is too low, maybe 45 mins if you enter from floor 1? 25-30 mins if you enter at an 80 save maybe?
Maybe the higher tier floor drops being nerfed somewhat and allowing them to be upgraded to what they are now via large numbers of tokens or Alexandrites (inc mythic upgraders raging), to keep them rare.
Ability to buy final stage upgrade items for relic/mythic/emps with large numbers of tokens (I know, I know but it's worth a shot).
More uses for tokens.
I have very limited knowledge of this event because I've more or less not bothered with it, I'm sure players that have done it more can offer better ideas.
