At least things like callings and quests show in advance, whether they will grant Renown or not, so I can decide not to do them. LFR isn't option for me, as it requires 170ilvl and obviously I don't have it at low Renown levels. And dungeons don't show, if they'll grant Renown or not. I just hate such systems. You waste your effort and there is no guarantee, that it will pay off. For example there can be hidden time-gated Renown cap, i.e. I'll do 100500 dungeons and will get nothing anyway. I just don't want to risk this way.
P.S. Is there any addon, that would allow me to rate WQs, i.e. set 1..5 stars rating, so I would know, what WQ I should do and what shouldn't. Problem with WQs - is that they have RNG rewards assigned to them, while having different difficulties, that usually don't match. For example just yesterday this WQ granted 105 anima, but now just 35. There are many of them. It's hard to remember them all. Remember, which ones are worth doing and which ones aren't.
