Additionally, you should macro your transformation with Perfect Armor so you can immediately rejoin with little issue.
Perfect armor is an entirely useless ability and casting it introduces a short delay during which other skills can't be used. It's better, and safer, to use either Humanoid Mech or Tank Mech then immediately jump to cancel the transformation animation and get the movement from jumping. After that you're free to use Mechanic Dash to dodge attacks from bosses.
Nexon America would never make a change to fix this so it's easier to just get used to the way it is.
Brief Bug Summary: Blaze Wizard's Orbital Flame projectiles desynchronize with character animations and are not being cast as quickly as intended.
More Details: In the Legion Raid as well as in KMS, Orbital Flame projectiles are synchronized with the character's attack animation. In GMS, Orbital Flame's projectiles will not synchronize with the character's animations. Projectile creation is staggered unlike in KMS and the rate at which projectiles are created is far lower than intended. Movement of already created projectiles behaves as intended.
Steps to Reproduce:
Connect to a GMS server from a home internet connection. Higher latency will produce more dramatic effects so connecting from a location further away from the server you are connecting to will make reproduction easier, likewise, connecting while the server is experiencing a high volume of traffic will produce a more dramatic effect.
With all four version of Orbital Flame at their respective max levels, assign Orbital Flame to a key. Stand on the ground and hold down the skill key to allow multiple Orbital Flames to be cast.
A successful reproduction of this bug will look like this:
This is an example of the desynchronization that happens in GMS. The projectiles are created inconsistently and unpredictably which results in a staggered stream of projectiles that is not continuous.
If working as intended, Orbital Flame will look like this:
At 13 seconds, the Blaze Wizard is standing on the ground casting Orbital Flame. The projectiles are created quickly and consistently. They will be created in a predictable and continuous stream until the skill key is released. Notice that there is no staggering in the creation of the projectiles. This is the same functionality that can be observed by a Blaze Wizard that is assisting your current character in the Legion Raid.
