I feel that mid way into “Wars & Tournaments “ one change of the defence team could be tried out = Allowed, so as to add a bit of involvement / excitement to at times a dead show… when defence is getting hammered.
This will make the play creative, interesting, otherwise
the 2nd half becomes a chore or is left out when the defence is hammered…
Similar change was allowed daily for our raid defence formations via Hero Academy
For tournament, i can kind of see the appeal. I know if my Defense team was performing (or not as the case may be), I might want to try something else…
If it were to go forward, I would want a strict limit and window imposed on changes.
eg,
tourney: once per day, not within 6 hours of the previous change
Although, I don’t think many people would use the feature. Many alliances use a unified tank colour and build a team around that. With emblems piled on the best defenders, there aren’t that many better alternatives usually.
