What is your favorite challenger mechanic? Don't know if that's what's meant, but I like battles where there are changes of weapons used by the opponent based on their health or changes as the opponents progress after battles as this is what keeps battling interesting for me.
Do you consider any of the battles that you do fun? A lot of battles are really boring and it's driving me crazy when I have to do grinding against weak opponents. I love being challenged, but in a way where success is feasible if I put enough focus/effort in it. (Given that I have the time to do it, which is not often the case currently...)
If you could battle other players, would you? no, I don't think so for the reasons mentioned already
1. What is your favorite challenger mechanic? I...honestly couldn't say on this. I don't dislike that some are more challenging than others (beyond stats) with certain adjustments where like, you can't freeze or can't use scrolls or something - but I prefer it in a format where it's timed based on curse activation, not on the whole thing.
2. Do you consider any of the battles that you do fun? Sometimes. I like challenging myself to a point - I don't like to feel like I'm fruitlessly bashing my head against the wall because the system is convoluted and confusing and there's no site created guide or information. What works for one person doesn't always work for another and the need to have nearly impossible to obtain weapons to beat certain challengers drains a lot of fun from the entire thing.
3. If you could battle other players, would you? Absolutely not. Aside from the obvious supremely unbalanced issues arising from folks with multiple capped pets and multiples of older/unobtainable tanked out weapons (things that you could get in multiple but cannot anymore etc)....I do not think it adds any kind of fun. I'm not here to fight other players, I like fighting challengers.
