Hello,
As noted by the many complaints about the design of this event, I will present my suggestion for a more appropriate gating of rewards.
First off, I understand the usefulness of giving rewards based on a players roster progress so I do not disagree with some progression in this event based on that.
What I do have a problem with is not even being able to play certain nodes due to the level requirements of Prof X, XWolvy, and 4Cyke. These three characters specifically are all now considered Vintage Heroes and were just recently released from several months of vaulting where any cover and level progress were severely limited to anyone just starting to cover those characters as I was when they were vaulted away. I feel that being unable to even try those nodes with my severely underleveled characters is unfair due to D3’s choice to return to vaulting for a period months ago. My limitation was not about choosing not to collect and use their covers, but due to D3’s choice to limit their availability. I will have the same problem if other Xmen are used on any future runs of this event. Teen Jean and others are also very lowly covered due to vaulting.
Solution: I think your intention could be solved by simply making those nodes hard enough to reflect the difficulty of not have your characters high enough. You would at least be able to take a crack at it with your pathetic characters. Kind of like the Crash of the Titans where I can at least take a shot at Beast with my two covered, level 90 Cho. I still can’t beat it, but every once in a while you can play and luck your way into a win in those fights.
It would still be pretty gated away simply by using difficulty, but with perseverance and some luck, you might be able to progress further if you at least have them rostered. In addition, players may use health packs as their attempts fail which could lend itself to paying money to replenish those needed for further tried, PvP, or other reasons.
Summary: Not upset with some gating, this has always been part of the design in a good way, but it could have been in a better way I think.
With much respect,
Killians
