I’m not sure how tagging could be called “critical for success”. You don’t need to tag raids to get troops like the OP would like you to believe. I’m not sure why he’s spreading this misinformation. I’ve never tagged a raid just to gain troops, and I’ve got better troops than treasure golems in every slot.
If this keeps up, players are going to keep their z10 raids private. Perhaps they already should be. Devs need to make a minimum damage to get anything from z10 raids, or get rid of the crappy troops no one who can actually hit z10 would have any use for.
