If I tower wasn't 26 floors, I would love for it to open up. HeRO's I tower is custom, opening to the public would be easily abused xD.
I went to an Itower somewhere else that had all the floors......I cried, I understood why they opened it up because it takes FOREVER to climb it only thing is that I Love, is that you can trap basically any mvp in a corner where they are stuck, and can't move.
And as far as parties go...............its the players skill individually honestly.
Put it this way.
Have Dragon Empire (think thats like 5 people) combined with Nya Nya (a good bit)
Let them go to a nameless 3 party, and they will rock that place down. Its not because they specialize in mvp, its not because they are mainly a mvp guild, its because of their skill levels they know their class and they have decent experience in different dungeons / scenarios.
If you have alot of people with good skills and that know how to play their class, nameless and even hell is easy. Coordination, and team work comes with having good skills in my oppinion. (if a priest cannot communicate well with others, if the priest is just shouting orders, that isn't a good priest) (if a priest cannot prevent a party wipe same deal)
BUT THATS JUST MY OPPINION
And as far as going to ice dungeon.......seriously if you can't handle ice 3 you shouldn't even be in nameless. Ayu gave an example of Saku and having links/buffs, but honestly, thats any sage or prof.
I was pissed at the requirements of lvl 80 for going to nameless before I realized it makes complete sense why they did it like that. There trying to get you prepared for it. No, you don't have the same attacks, and same threats coming at you, but its still preparing you for something like nameless in terms of teamwork And you don't even have to go to ICe dun, there are other places you can go for exp (your all lucky you have new world dumbed down)
And if your THAT lazy that you can't do a quest, or you can't FREAKING WALK and you have a mini map now that you can pull up INGAME to show you where to go? You defintly don't deserve wiping a nameless party and prevent that alchemist who worked so hard for his exp to drop 10% and not be able to reach 99.
