I was trying to say that the combo defender + specific leader ability can be very tough to deal with. Not either of them on it’s own but together. Some need a bit of adjustment rather than rework.That's not a problem with the Defenders, but rather with the respective leader abilities
I was sceptical about the last hot fix rebalance but after playing today I think it actually helped. I just wish they similarly adjusted NR engine swarm (e.g. pincer -1; inspiration -1; roche +1).
