I will stick with Maple Karstan all the way to 200

Ew. I'd rather not rely on needing 2 computers in order to play the game.

Why not? Get a character with max Speed Infusion (level 120 Striker), set up an old ass computer you don't need, set it in your map in a safe spot, go to it when you need it, press a single button, ???, profit.

It's easy and efficient and non-stressful.
