Given the changes it seems like it might a good idea. There are even a few in FS but it seems like the nastier ones are in FW and SP. Edit: since wavecrusher is lost, I wonder if the new shrine gib bg could involve shrine rushing with creeps and then sieging.
Not to mention FS has no worm synergy at all. FW has ALL of the Necrosis and Worm Lord, while SP has Implant. Creep siege doesn't really work except MAYBE on the FW map, because you won't get your SDZ that far out ever, since it goes away when the champs that extend it die.
I have been thinking that SL/FW might be interesting too since they have a few ranged arthropods and some ranged equip, to exploit the siege on certain maps.
