Funny, I just made a post in exactly the same vein. http://forum.eternalcrusade.com/threads/the-respawn-system-its-zogging-crap.59551/
Not really, you can detonate a Meltabomb(and any grenade) by shooting them. I don't know if meltas do it, but that would probably have to change other disarming would never happen as everyone would just start their melta burn right on their meltabomb. If I have time to kill a Rhino with a Klaw, you still have time for a Meltabomb to go off without anyone touching it.
One melee hit stops a Meltagun user, unless it is an Eldar then they simply outrun everyone while circling the vehicle.
I did say disarm. I'm saying that if we put disarming into the game for Meltabombs, we'd have to change Meltabombs ability to be triggered by shooting them otherwise no one will ever be able to disarm them because the person will just plant the bomb and then shoot it to ensure it goes off.
Not a bad idea, but I think an even better one might be to force melta-bombs to have a longer 'planting time'. Instead of being quickly drop-able/place-able, make it where they have to be stationary for a whole 1.5-2 seconds or so. Sure it'd remove the ability to put meltabombs on moving vehicles, which could be problematic. But in addition perhaps you could make them similar to mines where they either blow up on their native timer, or explode if a vehicle runs overtop of it, whichever comes first. Granted.. in no way do I think that meltabombs should be dedicated mines without timers. They should rightfully have timers.. By doing this you would effectively.. 1.) Reduce the effectiveness of meltabombs in melee (which honestly isn't all that bad right now anyway, but do you really need meltabombs for melee?) 2.) Make meltabomb'ing parked vehicles a slightly longer procedure (only by seconds but still, every second counts). Plus it'd be a lot harder for a solo tankbuster to knock out a vehicle (unless it's unoccupied) 3.) Make meltabombs more viable against moving fast vehicles. Also.. while this probably isn't the thread for it. I strongly believe all the vehicles need a longer 'dismount time' from gunner and driver positions. The passengers are fine, as is switching positions. But the fact you can dismount from your Vindicator/Warp Hunter/Ork-Uber-Kannon-Trukk-Thing-Of-Orkiness in such rapid fashion a little ridiculous. (And let's not even get started on how fast you can jump back into one of those vehicles).
