End Crystals are too Overpowered

End Crystals on Minecraft are too Overpowered, they can kill you in a couple of clicks, at the same time they are 100% Ping dependant, which means players with bad internet will struggle in placing crystals at a decent speed, There are a few ideas to make them less overpowered and let the rest of weapons in the game have an opportunity against Crystals

1- Cooldown: Crystals should have a cooldown, to make it less ping dependant and to don't let players launch another players into the sky with the crystals

2- Less Damage: Crystals can kill a player too fast, maybe setting the damage a bit lower can help to make a fair fight between players with crystals and players with classic weapons such as swords or axes

3- Damaging the one that places the Crystal: If you got a block lower than the crystal you won't get any damage and many players exploit this mechanic too much making the pvp less fun, maybe make the user of the crystal take 2 hearts of damage per explosion
