It's easy to stun, knockdown, air bosses, the problem is "timing" when to apply the corresponding skill, mechanic, that is what most players struggle with, specially against bosses that runs almost all over the place, why? because most of the time f8 party's don't have tank, and whoever gets aggro runs all over the place. total chaos.
Also, really hate those **** mechanic that throw you into air, like during the whole battle, (Sandstorm temple) it's just annoying as heck. Some classes can maneuver it, but still hit you a few times in between, losing tons of dps.
This **** mechanics... It's easy to speak of, but not really in practical for most of us (casuals). You don't have bosses pause in between battle so you could catch your breath to apply mechanic like they do in guide videos. Speaking of guides, most of them are useless, as they pause every 3-5 sec on the guide then talk about mechanic for a while, then rinse and repeat. As you watch it, it goes through one ear and out another. You need a certain ability to understand all that. Most people understand it, but majority won't, because (broken language, not clear enough, doesn't speak fluent English, speak to fast, doesn't explain well, doesn't speak same language, is an idiot through and through, many reasons) it simply goes from ear to ear and you think you get it, but when you do the actual dungeon you simply get lost within. mind blown.
Games are like math in a certain ways, if you are good at math you probably good at games, if not you get lost within.
In raids it's worse, only applicable to whales, dedicated people, top 1%. The rest is cut out from it. Unable to join, and If you want to join you need certain requirement, achievement, which is close to impossible to achieve, unless you play from when the game was release. The majority will never be able to do it, the only options would be swiping cards, carry run or maybe get lucky and get yourself a friend to invite you, which is unlikely, it depends (at this point being a female is a plus lol) In short new players will struggle a long while doing raids.
The game is fun when everyone can join and have fun. Good time "Misty wood" "ssp faction battle," Those are what we lack, open world boss where everyone can participate, doing quest, with worthwhile reward. Game is pretty much boring once you hit 60. Many restriction are put in place. there's nothing to do beside running f8.
They should really do something like adding an open world red zone arena, where people can chill, show off their wallet, skills and whatnot "like a certain game "flyff" the arena is super fun.
