Meso Explosion is an important key skill for Shadowers, but it is also quite a nuisance to combo with because it basically forced the player to press two keys almost simultaneously. The worst part is the inability to use it in macro settings.
A fair example would be Flip of the Coin, which stacks up to 5 times with a short duration of 120 seconds. The refresh is well off from other buff skills so I find it troublesome to count every second of the coin flip so it doesn't expire before I re-apply other buffs. The nice part about it is being able to use it in macros which I use after important skills to keep the stacks up without having to worry about it expire.
Both skills don't have any animation delay similar to Maple Warrior (and unlike Haste or Booster) so there isn't any problem casting thus making it perfect for macro with attacking skills. Except again, Meso Explosion cannot macro.
Meso Explosion should be able to be more automated like Night Lord and Night Walker and Wind Archer buff/passive, all which are triggered by chance. There are many more classes with the same technique, but Shadower seems to be the one that has to manually press another button just to cast that shred of flying particles.
