What other idea's if item focus passes do you think riot could go with?
I know the most recently mentioned one being maybe thought about an AP item pass. But there are definitely some clusters that can be looked at.
One is a range/melee split pass. I don't mean completely as extreme as what was recently done for steraks, but more along the lines of duskblade, and knights vow. Give the items more power for melee and/or reduced power for ranged. The energized proc's maybe could be looked at, rageblade most definitely needs attention in this, melee botrk users was a victim of this when it was the go to adc item a while ago.
An interesting one that I think could go well with what was done with what was done to steraks having a more constant improved baseAD scaling, and something that affects bruisers, is a pass to the common bruiser items to scale up baseAD like what steraks does now. Current items like trinity force and Thydra can be adjusted to have %baseAD scaling instead of bonus AD.
Another one could be taking a look at previously removed items and skills and see what can be brought back into the game in tweaked ways to not be so unhealthy/more useful.
in Summoner's Rift.
adjusted. The flat magic pen and passive don't really make sense together and it'd be cool to have it be split into two items.
in the summoner rift?
and switching grievous wound into 
,so every AP can take it (actually if you are playing a champion that doesn't build morello like rumble,viktor or anivia you can't get grievous wound vs sustain team,instead every kind of AP builds void staff)
before lethality lul
,
/ 
for example,a burst mage build is always:
which is actually useless if you are not brand or zyra (mostly for the 
+ 
+ 
(2900g full item) and its stats to 70ap 10% cdr 300 hp 35% slow it could be useful again
i'd like to see 
like an AP item (not hibrid AD/AP) , making it what the 
is for the AP assassins builds,or at last make it a REAL hibrid item and adding both AD/AP scaling on its passive,so it wont be anymore the akali-katarina-lb item
