It's a side effect from your point of you, but the raison d'etre from everyone else's point of view. There were WS I used other than GA. But most of the good non-axe WS are already available to WAR as it is now, especially considering the new WS: Vorpal Blade, Penta Thrust, Herculean Slash, Spiral Hell, Black Halo, Retribution. The only weapon type missing from that list is Hand-to-Hand (and obviously Katana and Great Katana, which aren't covered by your idea anyway). But you're not asking for any "useful" WS, you're asking for WS that have no merit in using other than to stagger mobs.
They do know how, but they see no point in it, because they simple aren't as useful as they WS they have. Name one WS a WAR needs to be more efficient, in any conceivable way (not just damage), apart from staggering.
And again, the WS you're suggesting we get access to don't fall within any margin of "effective". The only exceptions would be Dragon Kick, Asuran Fists, Black Halo, Guillotine and maybe Spinning Slash. For all of those weapons (except Hand-to-Hand) WAR already has access to good WS. And notice that 4/5 of those are also stagger WS.
To me that just sounded like this:
"We already have so much, and we'll get even more in the next updates, so it only makes sense to let us have more still!"
And I can assure you that's what it sounds like to most people (because that's what you said). You really don't see why people object to that? You say you want diversity, but the game already has diversity. The same argument you bring about "wanting to experience other things than a Great Axe" other people say to you about experiencing other jobs. Other weapon skills are simply available to other jobs. That's like a WHM wanting to be able to cast every white magic spell in the game, because it's just their thing, or a PLD wanting to be able to have every defensive measure in the game, because they're the iconic tanks. Some things are just not meant for certain jobs, despite how it may look like. If you want to experience other weapons, you already have the means to do it. It sounds like you just want it without having to do the work for it (i.e. level the required job).
Their envy is well-placed imo. WAR was already a very strong DD, arguably the strongest (bar relic SAM), yet SE pushed it a lot further. Balance was one of the aspects of the game that I always appreciated. The fact that a good WAR could out-damage any other average job. And the fact that a DNC could do the same. This is not really possible anymore, even great DNC have a very hard time just keeping up with an average WAR. Sure, they can do other things instead, but same goes for other jobs. That's not how it should be imo.
