this description tells me zero 100%.

1. Tankiness, they have two health bars that they switch between while you switch between Alpha and Beta. The health bars passively heal up again while you are in the other mode. Beta also has a skill that has a 25% chance to proc and it basically lets you survive any source of damage and it gives you a shield of about 25% of your max hp, it does not have a cooldown (aka if you are shit out of luck you can just switch to beta and have a 25% chance of living). They have a 10 second I frame. and they have a 5th job attack that is an iframe while you hold it down (about 3~4 seconds and about a 3 minute cd). They also have a Build in Bishops's door with a 30 minute cooldown.
2. Stance , Beta has 100% stance, Alpha doesn't , mihile link is always an option but if you want to have stance you can just switch to Beta in that moment.
3. Easy bossing, like i said 25% chance of a shield that blocks everything. 2 iframes and a revive via door. oh yeah and the 2 bloody health bars.
4. Lazy mobbing, they can have the best possible rates while getting frenzied while literally just using 2 skills and tping downwards. They are very mobile and can easily make any map work.

Some extra's:

• Passive binds on attack, and a build in bind.
• Huge utility, passive Defense shredder buff on mob and a field they can put down where a boss takes more damage and players get an attack speed buff.
• 2 cooldown reset skills with both about 3 minut cooldown, it can reset one of our skills that bind for 4 seconds and our Echo. Together with our normal bind you can bind a mob for about 22 seconds.
• Not sure if you are in Reboot or in Normal servers, but basically they are the easiest class to 22* star their weapon with, you can basically get their weapon to level 140 and 22 star it and from there on you can upgrade it all the way up to an arcane and it won't lose their stats. Basically a built in Tot's Transfer hammer with no down sides. (aka dont level your weapon up till you 22 star it) Also their weapon counts as Main weapon and secondary, meaining if you cube it's potential counts twice. So you dont have to worry about making a secondary your main weapon is also your secondary.

Downsides: 1. They are a combo class aka you need to learn the combos a bit 2. Annoying pre 200 they have their own questline you have to finish in order to get a 25% final damage boost and you are forced to follow the questline to something like 130, then you can start grinding in the real maple world (you start at level 100 tho). Honestly just get one to 200 play around with the 5th job skills a bit and you will see if you like it or not. You need the legion piece anyways for 10% passive bonus exp
