Did granbull raids get harder?

Against crunch it might be a challenge for Metagross.

The possible explanations could be your network being unstable, causing rollbacks and phantoms, or the raid having indeed been changed. Pokebattler puts L25 MM Metagross, no friend bonus, no dodging, at less than 120 seconds time to win and with 4 deaths. Meaning neither timing out or fainting out should be anywhere near possible results if you just keep pressing the screen.

Does the boss HP seem to recover gradually as you fight it down? That’s a bug that appears time to time (rarely for me, though). I’m generally very well able to take Donphan down alone, but it happened once that the HP recovery triggered and there was nothing I could do about it.

1. Make sure all MM Metagrosses have Bullet Punch.
2. It will be harder vs. Crunch, so dodge more often against it unless timing out.
3. Try not to faint out because Granbull will gain more HP.
4. If fainting out really is an issue, L25+ Aggron can help.

Granbull has strong teeth, when she Crunches, Metagross faints.

Possible reasons:- Your Metagross have crap IV (i doubt it and still MM is too OP)
-You are fighting a weatherboosted boss so its attacks are stronger
-The Granbull you faced had a full Dark type moveset that deals suppereffective damage to Metagross
-Somehow your team is wiped out and the boss regains health when you join the combat again.
-Unstable or bad connection can lead to bugs and attacks not registering so the Boss HP doesn't go down as fast as it should.
-You might be triggering the dodge glitch so that makes you loose precious time
