Anyone who picked ranged: did you take last stand or guardian? I can't decide

This is the hardest pick for me. I went F T W because I didn't want to grind raids.

So im thinking guardian is just better in 95% of content right? Speeds up all PvM.

I have infinite ranging pots so I don't care about the passive skill boost.

Last stand seems better at Zuk and maybe Hunnleff but seems just worse everywhere else because I didn't take raids.

Am I crazy for going guardian? People are shitting on it a lot but I think it'll save tens of hours off dragon cup
