Why was Shen's Q changed? I will answer to any/every comment.
Why was Shen's Q changed? There was no reason for it to be changed. It's almost as if it was because Rito wanted to just make a community cash grab where they would alter Shen to look cool but then throw him to the side as to get east cash. And before you say they changed it because of low Interactivity.. just don't. Many other abilities in league have this type of "low interactivity" and it could have been changed in many ways that didn't involve a huge floating clunky sword. Going along it's already reworked self they could've lowered the Q damage to make it less useful in trades, kept its sustain, paired his old passive Ki Strike to it as to make it like Akali's Q as to allow some "interactivity" and this would've allowed for more role versatility and easier balance as well. As for mid Shen enthusiast they could increase the AP scaling on his Q.
pairing Ki Strike to his old Q will not only add to its interactivity but also its versatility. It will force Shen to be more "interactive" top lane by rewarding him or encouraging him to prock his Q and will allow for him to keep his sustain, slow, and to not have a giant floatie. It'll also allow for Mid Shen to be a thing. Alrhough his Q AP scaling cannot be overtuned as the Ki Strike passive will be there it'll allow for more interactivity and will encourage the Shen to go in and play well to assassinate the enemy. Without any escapes he would be an interesting mid lane assassin that'll require precise mechanics and skill to play. It'll be a cool pocket pick and possibly a good counterpick against TF with his global pressure when mid. As for jungle it'll allow for him to actually sustain through the jungle and will still let him clear semi easily. Unlike his current Q which will not reward him at all his old Q can be used in the jungle and nerfed vs monsters if needed. As for support nothing much will change other than its play style. Instead of a very hard engage type it'll require set up before taunting into the enemy botlane.
As for another thing I'd like to discuss, I believe his current W should be replaced with a different ability so that he can have his 50% dmg reduction back onto his E. this way it'll actually reward Shen for landing his taunt whereas Shen would just be bursted down after 1+ something seconds of his current w. But the main topic is his Q.
If you have any questions comments or concerns about anything I stated please go right ahead and post comments. I'd like to discuss about Shen and why you think what you think while trying to elaborate on my opinions.
