I don't really see the point of execute smite.it will just put an even heavier reliance on jungle champs with a single burst skill like nunus bite eves ult etc.
If it was about removing the reliance on smite timing I am not sure it does that.
One of the things we are testing and hoping to get feedback on is how it feels when abilities (non-dot) can proc Execute Smite vs just basic attacks both have trade offs for sure.
Our goal is not to remove timing entirely, we still want to allow for hype moments like objective steals. Timing is still a valuable skill for junglers and we want it to remain that way.
The idea is that this is really shifting Smites power into your champion mastery rather than being something so ping reliant with cleaner controls and guidelines. While opening up new spell options such as Ignite, Ghost, and Exhaust.
The new spells should be nice for ganking focused junglers, and having Smite on every camp should also help when you are looking to power-farm.
