many forget that summoner had a huge setback when our 2hr Alexander was downgraded for many events to bring balance to the game. It was the only things summoners were used for but at the same time we had for once a place in endgame events. It wasn't the fact they gimped the ability so bad but to throw it in our faces that you needed 600 summoning magic just to get the full 60seconds out of it when the highest at the time i think was 517 was a total insult to us.
Still didn't stop people from using SMNs though

All it did was maybe make them have to bring more SMNs

Embrava took a much bigger nerf than PD did, IMO.
