Elixirs: When to use them?
So Elixirs like
and
have been in the game for some time now. When I see people using them in mostly at the end game, when they're full build and have nothing else to buy. I admit this is generally when I buy them too. But I was wondering; a lot of those times when you go back and buy an item, or just back and have only like 400-500 Gold and you can't buy anything SUPER important with it, only something small like
or
; couldn't or wouldn't buying an Elixir then + maybe a Ward actually give quite a bit of benefit over buying one of the small items.
Coming back with something like

could really hurt the enemy and more than pay for itself. Or are they basically only end-game gold waste items?
