I think they should change the “raid” section of the game.
Instead of 2 sections (global and tournament) >> it should be 3 sections: Evergreen calendared rare, epic and legendary tournaments. So newer players can constantly compete with 3s, mid range can focus on 4, and veterans can do all three.
Getting rid of Raid Leaderboard and replacing with ongoing 3 tourneys will encourage more variety of tank and flank usage.
Nerfing Tel and Vela didn’t solve the bigger problem with the game. The tel/vela proliferation is a symptom of a bigger problem of game balance … it’s not just 2 op heroes,
