Speed Infusion 11 does not work

Time to ticket nexon about it, i guess.

Hello Nexon CS.

Since the release of pirates many people have trained to marauder status. A few months ago a game related limitation was found by those in the community in regards to the skill speed infusion. By it's description, it's supposed to stack with booster and provide an additional +2 speed levels onto the weapon the user is holding. Due to the way that the game is set up, certain classes remain immune to this buff, including buccaneers who have it in the first place.

Knuckle®s have a natural speed of fast (5), so with booster that makes it faster (3). With speed infusion at level 1-10 (-1 speed level), that makes it faster (2). Once speed infusion is 11+ however, the speed is increased once again so knuckle®s SHOULD reach fastest (1). Since a few months ago many have rumored that speed infusion DOES NOT affect weapons that should go lower than faster (2), as the game does not physically let them break that cap. This also means that other weapons (Some 1h swords, daggers, claws, and crossbows) become immune to speed infusions effect. This rumor has been confirmed as of today by a buccaneer who tested various skill speeds with level 10, and later level 11 speed infusion.

I know for a fact that other maple versions, as well as GMS beta allowed for the speed cap to be broken, but for a reason left for speculation by the community, GMS does not at this time.

Is this a bug that should be fixed, or is making speed infusion inherently useless past level 1 to the class who receives it the intended effect?
