Hey, there. Just to give some context (I'm not bragging, I swear), that post about Shen's E width that Riot responded to was something I posted. And to be frank, I don't think Riot was willing to do much follow-up on Shen after the rework. I was hoping they would at least ship out the E fixes, but we haven't heard anything about those. Here are a few things I would like to see fixed on Shen, should they look at him again.
#1. Decrease the tether range on his sword/increase the missile speed.
In general, Shen's kit feels clunky and slow because of how long the sword takes to get to places. While I personally have grown accustomed to it, it discourages newer players from playing Shen because it takes a while to get used to. In general, the sword feels kind of slow and requires lots of thought to utilize correctly, which shouldn't be something commonplace on a simple champion like Shen.
#2. Make the Q affect enemies in a small AoE around Shen.
Why, you ask? Mainly because champions who can kite Shen have no issue doing so even if Shen is right next to them. Many Shen players, myself included, would like to have a small AoE effect of Shen's Q so that opponents who are right in front of you don't laugh and walk away. If giving the full buff is too much, a small slow would at least be appreciated. This is so that Shen is rewarded not only for pulling the sword through his opponent, but also giving him some breathing room in its utility by allowing him to catch up to ranged champions.
#3. Give some clarity and power to Shen's ultimate.
Shen's ultimate is by far the most central thing to his kit. A global teleport paired up with a shield to protect the ally he's teleporting to. But in this age of assassins and ADCs, the shield sometimes is not enough. A 250 / 550 / 850 shield is fine and dandy, but not nearly enough to save an ally in danger anymore. Seeing as how Riot is probably not going to nerf Thunderlord's (which can basically take off a good portion of the shield itself) or burst in this meta, it's only fair that we see an incremental increase of something like, 350 / 700 / 1000 to keep up. It might seem a little strong, but trust me. There are times when I ult to my ADC who's half health in a fight against the enemy ADC and by the time the cast time finishes they're dead. During laning phase. This one is up for interpretation.
As for clarity, a change I have been requesting for a very long time is an indicator for Shen's ultimate. So many times I've had teammates flash away from a close fight WHILE I was ulting to them. While this may be a symptom of low elo at times, it doesn't make for a fair disadvantage. A way to add some clarity to Shen's ultimate without creating too much clutter is by adding the action-line effect to your champion, similar to the actual inside of the shield. That way, your ally knows Shenpai is on the way.
Let me know if there's anything else you're wondering about. I'll be more than happy to answer any questions or listen to any challenges to my ideas.
