Ok well I'll grant you that I could never get 20 kills in a battle server with a long maul, and it would be harder to do than with almost any other weapon...I still don't think that makes it underpowered though...I think of it more as a support weapon (or a situation specific weapon). I also wouldn't expect to get 20 kills as an archer or pikeman. It swings very slow, so I think that's the main reason you wouldn't get as many kills with it.
I don't see how you can justify a speed buff for it, since it's the longest crush through weapon in the game. That's the trade-off for it. You get a long crush through weapon, but it's one of the slowest weapons in the game, and not as strong as other crushthrough weapons.
37 blunt is a great deal of damage being dealt, I can't see a justification for increasing the damage or the speed of it. And I think it's very useful in siege maps, and can see it being useful on battle as well (in strategus) as a support weapon. Once you have the weapon chambered, it's not really that slow to swing forward.
I sure as hell wouldn't want to take it into the battle server on NA1 or EU battle server though...I think I'd get reamed most rounds. But I don't think that qualifies it for a buff...
But thats not how c-rpg works, or have you been playing another game?
Every weapon should at least be at least a viable weapon in battle or siege, but i believe that it is not viable in both scenarios. In strat i would be very surprised to see anyone use a long maul as its just a pile of rubbish.
With Nubert no longer using it in siege and Nicko no longer using it in battle, why should it only be confounded to strategus sieges. Compared to the Long Maul which more than viable in these fields especially strategus.
I will see people use a Long maul in battle and get rid of it very quickly because they realise how crap it is, i only use it in battle because all other polearms have become boring for me and it is just a challenge to do well with it, without support the Long maul is useless.
As your support argument it is not valid, the longspear and pike are meant to be support weapons but they do fine in many different situations in the right hands.
Every weapon should be viable in each mode and have somewhat a place on the battlefield
With Nubert no longer using it on siege, Nicko no longer using it in battle
