ganks are a meta, they can't be stopped, or it will cripple the freedom of defenders, but a few people likeminded about the problem has made a collaborative brainstorming to make ganks harder, we propose to make it so that, specific grenades can and will be able to destroy specific blocks in seiged claims like doors(iron doors not included), fence, fence-gates, levers, buttons, pistons, sticky pistons, redstone, tripwires, strings, elevator blocks (redsand stone) to basically make ganks a liability. the destruction of these said blocks using a specific grenade makes normal doors and blocks unsafe, people cannot just in gank holes without a threat of breach, as it promotes the attacker to breach into the main walls (suggestion also include that elevators can be used by anyone who's combat tagged, regardless if defender or attacker side) , though I do not know the extent abusability of the suggestion, but it seems fair as of this moment.
