Sorry for the essay, but-
I think this is the wrong way to nerf the greatsword. I’ve got lots of experience with van swords(80,000+ kills), and I don’t think this is the right way to approach the too-fast overhead problem.
The problem with the greatsword overhand lookdown isn’t with how fast the windup is. The problem is the animation/tracers. With a greatsword lookdown overhand, the tracers seem to hit before the weapon model hits. It’s the same problem as the ‘handle hits’ from polearms(those were patched out, weren’t they?). If the greatsword overhand tracers were changed to begin farther back, we could have an extra .1s grace time before being struck. Appearances would match up with player expectations and they would be able to parry it properly.
I think that by giving greatsword a .6s OH windup, it will become just a weak zwei. It will lose it’s role. Yes, it has significantly faster combo times, but these faster combos are still relatively normal and easy to parry - they’re not as great as an advatage of the huge power and draggability of the zwei. There wouldn’t be much of a reason to choose greatsword over zwei.
My main problem with slower windups on the greatsword is this: A .6s windup in CMW is on the slow side. Slower windups give the enemy much more of a chance to interrupt or deliver a profitable hit-trade. I think increasing such vulnerabilities for greatsword vans would make them easy meat for sword knights and MAAs. In my experience, sword vans are already an easy kill for a sword knight.
The greatsword van is a brawler class. To do work, he has to get in with the knights and adopt their role as front-liners, whacking and parrying and taking hits. Spear and halberd vans don’t have to do this. They have the advantage of extreme range and can stay well out of danger while still delivering hits. But greatsword really isn’t all that long compared to knight 2H weapons. All knights have to do is land one parry and they can close the gap. Then it’s a guaranteed 3-hittable knight vs a likely 2-hittable van. Is that okay? All the van has to do is hit the knight one extra time. But I think that’s where the .6s greatsword OH windup would show its weakness. Any veteran knight worth his black hat is going to be able to take a nap and still make a hit-trade with a .6s greatsword OH.
To summarize the above: a slow windup greatsword is an uncompetitive greatsword. Zwei users don’t often brawl - they skirt the edge of the fight and land support hits before they dive in because they know their weapon is too slow to challenge the reaction times of knights in a face-to-face fight. If the greatsword becomes that slow to windup, I think it won’t be competitive enough vs sword knights(the most common knight) in a brawl. The van will be stuck with a slower weapon and less effective health. Providing equal skill between the knight and van, and predicting an outcome based on the numbers, it’s a likely loss for the van. In a brawler role, the greatsword van will be obsolete. But that’s greatsword’s main role.
Maybe I’m just nervous because greatsword is an old favorite of mine. Maybe I’m wrong and a .6s windup OH will work fine in practice. I don’t know, I’m still downloading the beta; I haven’t yet tested. When I get it DLed I’ll test a bunch. I just wanted to get some discussion out there. But my past experience leads me to believe that greatsword will be made sub-par, like the falchion and grand mace before it, if the nerf goes through in this state.
If Torn Banner is gong to keep this windup nerf, I’d like to ask for a .65s greatsword thrust windup. It seems odd that the thrust is the same windup speed as the zwei thrust(with slower recovery, what what?), and yet .1s slower to windup than knight sword thrusts(.7s vs .6s).
TL;DR: The GS overhead speed problem is one of animation, not windup speed. I think that a slow windup greatsword will be too similar to zwei and be uncompetitive with knight 2-handers.
