Yes, same issues in 3000+ rank, those elite blasters spoil the game, since they also heal buildings and fences.
But there is a solution, use sword rain to kill them all at once, then it’s goodbye healing and you are fine.
A lot of lower ranked players are not that fortunate, their swordrain/frost/hammerstrike are not powerfull enough to beat those blasters with one direct hit and so they lose fights they should not lose.
But it’s worse when being attacked by them and don’t have that elite boost yourself. Players 10-15 hero levels lower and rank 1000+ lower can beat bases normally unbeatable for them. And if such a player adds you in their favorite list, you will lose trophies a lot. I fell back from 3750 to 3300 just because a few players added me to their favorite list and kept attacking me 12 times a day. But for me trophies aren’t important.
This elite blaster is spoiling the game, that healing effect should be limited to max 1 troop and not full heal but max half of life plus blasters should not be able to heal blasters.
