As someone whose actually been playing ARAM more so then even Normal matches, I'm in the 100% agreement that the Snowball/Mark summoner skill is absolutely broken and stupid.
The idea behind it was to allow non-gap closers an option to get in, however since it's available to ALL champions you've basically made this the most abusive summoner skill in Aram. Champions like Irelia, Akali, Talon, Fiora (just a few examples) were already strong champions in Aram Pre-Snowball however with this implementation it has literally skyrocketed them into a level that makes them absolutely unstoppable.
Irelia was a force to be reckoned with before the Mark days because starting at level 3 and having the ability to buy an item such as Sheen right from the get go along with pots completely negates her usual early game weaknesses that you would normally see on a map like SR. She is a champion that sports gap closing, slow/stun, healing and True Damage all in one.
So as soon as she finishes a Tri-Force + Merc Treads and builds tanky onward, she simply can no longer be stopped. Remember, this is Pre-Mark Aram, but now with the ability to give her basically another dash, she's gone from a Great Aram Champion to Elite Status. Reasons why is because this allows her an option to dive freely under turrets while also giving her an escape dash capability as well.
One of Akali's weaknesses in Aram was that Pre-Level 6 she could be bullied, but once she got to Level 6 and if played correctly would become an absolute Monster, however this is no longer a problem for Akali Pre-6 because of the Mark/Snowball. What Riot has basically done was give Akali 4 Dashes considering her Ult allows her 3 gap closers already.
Fiora is another champion who was already incredibly powerful Pre-Mark Aram and although she has a gap closer at the early levels, she could be cced, and had to contend with a Wall of champions in order to get to the back line.
Now all I have to do is hit the Snowball anywhere near close the enemy squishes and it's Free-For-All for Fiora to Ulti while crushing them at her leisure. Did I mention with the Mark, she now has 3 Dashes? Yes indeed.
Darius has become completely broken with the current setup, and we shouldn't forget Yi who was already a game changing Champion in Aram, but with the inclusion of the marks he's become one of the most broken champs in Aram. The amount of stupid Fiddlesticks can do with his Ulti now is unbelievable. I've seen Fid players cast ulti, and launch their marks to chase squishes well in the back line, while ult is still running.
Numerous other champions who have AOE ults like Amumu, Wukong, Kennen, Galio were never under performers within the previous, however it's just that now it has become significantly easier because they either now have a gap closer or two in some of these champions cases.
Just how do we stop Mundo now? You introduced Warmog's which is an item that Mundo thrives on while also giving him an option to dive? Sion along with his ulti and the ability to have a second crack at life allows him opportunities to just break turrets down with essentially two health bars, the Snowball is Amazing for Sion because he didn't have a gap closer besides his charge. OCV.
Their are champions in the game of League whom were never implemented without a diving skill for a reason, but with the Marks you've given champions like Darius, Garen, Mundo, Singed etc gap closers!
Riot has basically ushered in a stupid trend of people flying in at level 3, with constant bombardments but more importantly it has completely devalued what strategy that was available in Aram.
I would rather deal with Lux, Nidalee, and Ashe Pre-Mark/Snowball then Wukong, Mundo, and Yi in the current Aram.
My reasoning is that Lux, Nidalee and Ashe are squishes and can eventually be dealt with as the game progresses, however with the current Aram-Meta, champions like Wukong, Mundo and Yi will never EVER fall off from start to finish because they never did in the previous Aram either.
Not to mention that they actually have the ability to build tanky w/o detriment to their champions (besides Yi) and the longer the game last the more powerful Wu, Mundo and Yi will become.
What makes the Mark/Snowball more irrelevant is the fact that the champions whom were terrible previously in Aram are STILL TERRIBLE now even with the introduction of the Marks, just go and take a look at the statistics! Champions like Eve still sit at the gutter of the barrel in terms of win percentage even in the New Aram.
However in return you killed off many of the other viable champions in doing so_, while making the majority of gap closers who weren't weak in Aram either significantly stronger or flat out broken.
Their is no argument here that with the Current-Meta we have Far Less Viable Champions now then we did prior to this update.
Once again, Riot never ceases to Amaze me with Silly...well, more like stupid implementations without fully realizing the repercussions of what could take place. If they just Looked at the Dive Stupidity that took place during the Aram Poro King Event, they would've known full well to have never set this into motion. It really makes me wonder if they ever bothered to look at or test these things before fully implementing them into the game and believing that it was an Excellent Idea.
Revert Aram back to what it once was.
