I’ve already (mostly) said my piece, though I’m sure I’ll add a few thoughts in other threads once the events are live and I’ve had a chance to play them.
But one thing I think is getting lost in the weeds: I actually like the gameplay of Arena, same as I like the different mechanics of Treasure Hunt. As an early player, these were my favorite modes.
What I’ve never liked, and what got me to move on from playing these modes at all, were the smaller-rewards-per-unit-time.
It just wasn’t profitable to play in the Arena. It might still not be, if the pity-timer balance isn’t worked out well (thanks @Smash for validating my line of thinking; I guess being around for as long as I have, or maybe just being Metagross, has given me secret psychic powers that allow me to see what the devs are up to before things go live ).
But if it is made profitable, I do look forward to playing, not just grinding Imperial Deeds.
If the draft pool is improved, and if there are some checks in-place so that the entire mode doesn’t become too-hard a la @Fourdottwoone’s point about difficulty creeping up as more lucky hyper-synergistic builds crop up, and if rewards feel rewarding per-unit-time again, then I will more than happily play, and have fun doing so.
