for alts, now collecting runes and titan stone is super easy. increased drop rate + 2 sure drop from lei shen and sha of pride. that makes is fast.
a portion of my main's secret collection was before when lei shen had 100% drop chance, so for 2 weeks, i went empty. that was frustrating. now its super easy. on my 2nd hunter, i got the sigils in like 2 weeks just. its the pvp part i can't get past, can't find a couple of free hours. other than that, rest is easy.
So, no need to make it account bound. something rather be kept bit out of reach so u work toward having it.
