The constant use of the word “bust” is absolutely terrible grammar. You don’t bust open crates, you BREAK them open, or you just open crates. You don’t bust up creeps or enemies, you BEAT them up.
Skills, discs, etc. don’t buff heroes, they BUFFER heroes. “Buff” means to polish, shine, or smooth. “BUFFER,” the correct word, means to support, shield, cushion, enhance, or protect.
