It’s not for the most part, or at least not more than other modes. Tickets are essentially like war/raid cans. Obviously spenders can always buy a higher score in Endurance mode, but the modes seem quite balanced in frequency, and there’s a decent number of tickets going around so you can save up and try for a big play.
Champions arena should really be limited to tickets though, that would be fair and lead to more interesting play.
No, it’s not really a raid event. I quite dislike those, but I like Arena quite a bit. More planning, different rules, the outcome of the battle matters much more (losing, or even losing a character, has a significant cost). Also, a raid event takes dozens to hundreds of battles and is mostly a completely boring grind. Here battles matter, so the five a day can actually be tense and fun.
I’m not sure I understand the question.
Other points I would like to make:
- The player base is not used to pvp events where you don’t have to grind out hundreds of battles
- The mode has many of the same issues as other league-based events, and in some ways have made the problems worse. Leagues mix strength and activity in weird ways, and the balance tends to mean people are better off in lower leagues. This is difficult to fix, but needs to be looked at
- I think the endurance mechanic itself (characters wearing out after use) is interesting and could be developed further.
