I say, why not, I would definitely use it because I like to explore the world these guys spent hours making. I am the guy that you will see scaling mountains not usually scaled in games like WoW, WAR, and Oblivion, because I like finding random things that I know few others will take the time to explore. It makes me more attached to the game because I know that If I can find this thing, post it somewhere, and have responses like "Where did you find that?" I will be a happy camper to know that I went through the trouble to find it, and it was appreciated. Sure I sometimes find those spots where you fall off into nothingness, but with a feature like a hearthstone, or Book of Binding, You will always have that to get you out. let the 30 min -1 hour cooldown be your punishment for finding that place, and do be an idiot and go back"
"I find jumping annoying"
I find babies crying annoying, but I don't go up to the parents and say "Can I please kick your baby? He is rather loud"
Everyone finds annoyances, It is called "coping" which bluntly means, shut up and quit whining.
I remember when my friend first introduced me to FinalFantasy XI. I started in Sandoria, went outside to kill some things, and these puny little hills were making me walk 500 feet away in an already slow walking pace game. That turns customers away, especially in the Modern MMO "standard"
"Jumping looks to cartoony?"
All I have to say to that is WTF?!?!?!
are you serious, go to your mog house and what the **** is that floating in the room? Lol you have got to be kidding me, when you say FFXI is a serious adult game and jumping would make it look bad, when I see 2 foot cabage patch wannabees running between my galkas legs left and right. I will never, EVER take this as a serious response to jumping because When I see a game where one of my most serious threats at level one was a rabbit. I actually laughed the first time I killed one. I was like, this is a serious enemy?
I am in no way making fun of the game. I enjoy the lore and just about everything about it, but don't tell me it's serious, and not cartoony, after looking at this http://media.photobucket.com/image/Tarutaru%20and%20moogle/whitetigre_2001/FFXI/tarume.jpg
If you ask someone, anyone for that matter. They will not say those a serious looking creatures. They will be more like "SOOOOOOO CUTE!!!!"
All in all, the positives outweigh the negatives in my eyes. Invisble walls are easier to make, the proper pathing routes
