War needs a rework. It’s a Coliseum clone that you’re forced into playing by pressure from your guild.
To differentiate it from Coliseum and make attacking more flexible, each lineup should be fought separately, as opposed to in consecutive waves. Fighting one row of heroes at a time would allow players to make more strategic choices about which opponents they fight. Another benefit would be fewer game crashes and shorter loading times before fights.
The number of bonus fights should also be doubled or tripled, to make up for the 200% increase in demand. Sharky, Off Roader, and Roller Diva would also need to be adjusted.
Aside from that, there’s a change that should be made to the rewards system. After all the effort winning a War in Legendary requires, it’s absurd not to give players any form of tangible reward. Guilds should receive at least one war box with every victory to reward and help motivate their members.
