Murksphere is Awesome

Above is the item line for a support item in BMB. I just want to take a moment to express how amazing it is. it's not that it is over powered, far from it, but that it brings a lot to the support role. It is a fun item that encourages trades and can play a game of cat and mouse about who triggers the shield to proc some extra gold on the support side. In addition, it can be used to really help those champions that struggle early game (looking at you Taric) due to mana issues. A free shield helps them sustain a bit and a huge burst of CDR later. Now, the item come with it's weaknesses, mainly the threat of an all ins, but it excels with trades. How does this stack up to other support items?
- Good for passive supports that like to farm it up.
- Good for support that like to poke.
- Excels for Supports that like to go all in.
So where does
fit in? I see it playing a role in which supports that want to trade take advantage of it. They are not looking to poke but rather trade some damage back and forth and come out on top.
would all be fine candidates. Now I realize not everyone plays the same and this may just be my own play style benefiting from it but I would love to get other people's impressions of the BMB support items.
