Recent lags on EUW are caused by server. Just look at game's ping (CTRL+F in-game) and then open your resource manager. If game says less than resource manager (atleast by 2x, because there is always a minnor difference between these two) there is server lag, not your internet (OR your firewall, router delay, but sure as hell it's not bad connection speed). For past few weeks (actually it started one week before EUW got IP boosts) i've been playing with 250-400 ping for no reason.

But back ON TOPIC: As you say, getting bonus by AFK/DC should be implemented to lag spikes. Then what threshold should it be? 500 ping (DC threshold- turning off modem sets ping to 500)? 1000 ping (Still able to command, but not able to see what happens on fields and when it happens)? Furthermore, in that case game should also get info on your connection availability, quality, packet loss and jitter. Why? Because you can have fast internet, good quality, but have packet loss at router, which makes you lag in-game, but not in server. OR you can have very good quality, no packet loss, but have some jitter, which makes game read your ping wrong. Just imagine someone going as Vayne with 1k armor/MR AND glasscanon build. Think it's not possible? Just raise your ping without laging connection and you have it. Easy as hell. Might as well do it editing packets. Maybe even delaying some of them (those, who report connection quality for example).

TL;DR: No, just NO!

Sorry for wall of text. I just had to.
