Unrealistic interactions

I have noticed that there are many interactions with certain things that I think need changing due to them going against the logic behind them. A few examples are things like champions completing a dash ability while cc'd (i.e. ezreal shift while getting hooked, hecarim completing his dash while snared, etc.), casting abilities while stunned (like trynd ult or sort of when vi is mid ult, I understand that she shouldn't be able to be cc'd by anything else, but charging at someone and uppercutting them while stunned, which is basically the same as being unconscious, that should not be possible), and lastly healing while either hourglassed or bard ulted, the only one I can think of is swain at the moment, but still if you can't take damage, even DoTs that are already inflicted, you should not be able to heal. If anyone has any other examples please comment them so that on the chance this gets seen it might be fixed or if you think they don't need to be changed let me know why.
