I've been playing block wars ever since it was out in the beta lobby, but i noticed that none of the powerups are stealthy. so here is the fix, Invisibility, and EnderPearl. Invis would be like speed and jump but it would last a little longer and only affect you it would also keep your armor on but not show it(like on hypixel) and enderpearl would be like TnT but have a Time limit to make it fair. these would add a whole new layer of strategy that the game lacks becauase currently blockwares is just your average CTF.
