Do you only do the monster climbing stuff if you're playing a Warrior? Or can, say, the magic classes, climb also?
For people who have played this before...what is the most fun to play? How do the play styles differ? How easy is it to switch vocations?
Monster climbing is generally meh if you don't use daggers. Every class can do it, but all of them are limited to basic light attacks while doing so(mages can use heavy attack but it bounces them off the monster, useful to dismount while doing damage then float away). Daggers however have a few skills that can be used while mounted, specifically Hundred Kisses(and it's variants). Assassins can also use a sword skill while mounted but Fighters don't get that skill.
Climbing still has some advantages, such as baiting the monster into certain moves(like trying to swat you off its head or jumping on its back to the ground to try to squash you) which let the rest of your team do damage. It's also useful due to the targetted nature of the attacks. While for some classes this isn't useful(say Sorceror, who use massive aoe skills anyway), if the target has weak spots it can do more damage than doing normal skills in other parts(easy example, light attacks in the eye of a cyclops do more than skills in its feet).
In my opinion, the most fun are Strider based classes. That is, Strider(duh), Ranger, Magick Archer and Assassin. Mostly because I think dagger fighting is the most fun, due to the climbing stuff and the fast speed, move cancel, dodge rolls, double jumps and so on. Note that Ranger in that list is way way more focused on using the long bow than daggers, so I'd say it's at the bottom of the list for me.
The casters are cool to play for a bit but I tend to find hem boring very quickly since most of the gameplay involves charging up big spells then releasing to kill everything at once. The feeling of bombarding a pack of stupid wolves with meteors is definitely great the first few times, but later on it's kinda like, eh.
Fighter based classes(that is other than assassin) can be fun, but I find them less rewarding than the Strider based classes. Mystic Knight is unique enough though that it's definitely worth trying.
In the end however it's all a matter of taste. Oh and switching is super easy, just talk to a NPC to switch, then you need to switch your gear but takes like 10secs most of the time.
