So I took a break from ESO and just came back. Was curious to see what balances/changes/updates were made to ToT.
My general findings? None. It's a time capsule indistinguishable from when I left, except there's even fewer people playing it. None of the RNG spam decks have been nerfed. No new decks have been added. The game still heavily favors and rewards RNG spammers, so the "usual suspects" that prefer RNG spam decks/combos like mora + red eagle, druid + psijic, crow, etc are still playing... but mostly with just themselves. I caught the last day or 2 of the last season and only 600 people were in ranked competitive for the entire season.
All the players that preferred the skill/strategy focused combo of decks that I enjoyed my games with have mostly moved on, almost certainly tired of the "gambling addicts" making every game a race to see who gets the best rng and end the game in 3 minutes before it can be an interesting battle of skills. Also the new players seem equally turned off by the RNG spam after a quick read of the forums, frustrated and vocal about how upset they are that luck is the prevailing factor.
I'm guessing the devs just totally gave up on ToT since it is just as imbalanced as when I left and it has no new content. It's a shame. It has all the foundation of a really fun card game, but just like most of the content, they listened to the loud/vocal casual players over the skilled/dedicated players, focused on a system that could allow casuals to "get lucky," and drove away anyone serious. This is exactly what happened to Adventure Zones, trials, and PVP. The casuals still don't do any of that content and the end gamers got bored and left. Oh well.
