Mark/Dash is the dumbest thing in the world

I was just in an ARAM match, my team consisted of Me (Nidalee), a Lux, a Gangplank, a Xeroth, and a Veigar. Pretty OP poke comp for an ARAM game right? Well we had no tanks so once the first portion of the game (Constant Poke under tower) was over the game would become much harder for us, especially against the enemy team of Sion, Fiddlesticks, Blitzcrank, Gragas, and Ahri. In the long run they would eventually beat us, but thanks to the awful new Mark, they were able to destroy us from minute one while we waited under the turret. There is a reason the champs are melee, they are stronger in close quarters, so why not give them a spell with a ridiculous range that can hit champions OR minions, and allows all those beefy, cc crazy tanks and bruisers to fly into a squishy ranged poke champion. Oh and its only got a 20 second cooldown so no problem if you miss. Mark is seriously way to strong, and it honestly makes ARAM not in the least bit enjoyable anymore. Why even bother if Sion can just mark you under a turret, fly in, and then slow you, and have all his other teammates do the same. There is a reason melee champions arent overpowered, and that is the fact they have to get near you to do something, but mark just gives them a 20 second Caitlyn ult ranged, invincible Lee-Sin like q. Although I would love to just have it removed, I'm all for it being a permanent ARAM spell, but it needs some serious nerfs. I normally would play ARAMS to have a fun, quick, and relaxing game, but I plan to stop playing them now, because of how much this new summoner spell ruins it.
