Mysterio and the buff program (Warning; Long post! TLDR at bottom)
Why buff Mysterio?
So after seeing the recent buffs given to champs I couldn't help but think about one thing: "These buff types are almost meant for Mysterio". Now before I get into this I wanna point out this is not an attack or complaint about the buffs. I actually like a lot of them and think Jane her buff was a nice thing to have, but it is not the focus of this post!
(Also quick disclaimer, English isn't my first language so I will try my best but I might fail)
Looking at Jane her buff she got the following changes:
-Synergy in basekit
-Sig ability in basekit
-Some number changes
I think the fact Jane was a rather underwhelming champion prior to this buff the changes were considered to be "minimal" by a lot of people. However I think Mysterio is in a lot better position and could easily reach a much better state of gameplay with this type of buff without becoming a super OP god-tier champ that breaks the meta.
As it currently stants Mysterio is not the most popular champ and I think that comes down one tiny design flaw. The guy cannot acces his utility and damage at the same time. This forces him to choose and TBH, the damage and utility is rather underwhelming without putting all focus on it. That is why I think a buff like Jane got would be perfect for Mysterio!
Improving the Fishbowl
Looking at Mysterio his kit I think it is pretty clear to me where to make these changes:
-Peni synergy basekit
-Sig ability basekit
-Change some numbers
-Bonus idea: add a new synergy
I think if we made the synergy and sig basekit for Mysterio he would have a much easier time inflicting damage and using his utility. I also think he would not be anywhere near overpowered or meta changing cause these things already exist and aside from Abyss Thing you rarely see Mysterio used in game with all these options open.
I also wanna toutch on some numbers of him. First of all I think the SP1 is clearly an ability that only serves the defense use, and I am okay with that. So I won't change it. However his SP2 powerdrain has the option to be a lot better on offense. Currently you can get up to 7 seconds off power drain. With 6% of max power drained per second. This means at most you drain 42%. If we increased this 6% to a higher number or we increased the duration it could be a bit more appealing. However I do wanna throw out the option of maybe making it a power steal where 50% of power drained is granted to Mysterio (maybe make it so this only counts when helmet not broken). Lastly the heal block. 1 second basekit + 6 possible seconds feels really short. Maybe make it 5 seconds basekit with extra time based on gas.
Lastly if we make the sig his basekit he is gonna need a new one. I wanted to offer a personal idea of mine I think fits the character rather well:
Grand Illusion:
Once per fight when Mysterio would be knocked out he instead becomes damage immune for 1-5 (depends on sig level) seconds + 1 second for each gas charge he has. Additionally he enters his 2sp miss phase for the duration of this ability.
TLDR
Mysterio is a champ that can benefit from a Jane style buff. Make the synergy and sig ability basekit. Change some numbers and he is good to go. This won't be OP cause the options are already in game for him to use the synergy and sig but he is still rarely seen.
