destroy the core

BlockWars Giga has slow matching so these two might not be playable so adding these to the 5v5 makes matching easier. Also, when playing with 100 players, the lag can be severe depending on the device.

In the gamemode "destroy the core" in giga blockwars some time after the gamemodes return a change was made which caused the core blocks to take a really long time to break, in this clip it took me around 50 seconds with an enchanted iron pickaxe, and I just wanted to ask if this is intentional...
