Most of my ingame stones work better than ms, and I only use elixirs when comping with HP(I try to use elixirs on all ms stones, though), most of my other comps are just as good as ms stone comps. Usually for both ingame, and ms, I get around 130+ ap comps, sometimes higher for either stone(or lower..curse you mins).
But hp comps are usually better with ingame stones+elixirs...or its just me ._.
And always try to get Attr capsules for comping, my comps are 20%-40% better than others I see, and this is using with and without elixirs. @@
