It always depends where you guys play. If you play somewhere around top 100-200, it's different then top20-50.
In top20 nobody cares about chests. Every team plays just for ELO. Start - lead - dome - bye.
For chests wars there are so called feeder clubs, which usually play lower.
Every time i see posts on Facebook "why are they hiding???????" i want to ask "why did you dome them?". Why didn't you guys organize yourself , work on a good strategy so they don't lead?
10 vs 20/25 - there's no other way to play.
10 vs 10 - it's different thing, but even then it costs a lot of recourses to lead (jackpots, umbrellas, pumps, war items etc). In any way every team decides what's the best for them.
Instead of bullying you can try to do it better next time. Or use Facebook War fan page and try to find your opponents and agree on an open war.
Good luck to everyone!
