Ulti-Funnel-Reaver requires more moving parts and experiences more attrition from the artyporc. It is also slower than Paladin while having lower range.

I think it can probably sometimes be used as a tempo push though. Just keep that paladin running as you erase its base and reclaim the wreckage.

But in the long term i think it is less reliable and more expensive.

Also annoyingly even if I kill them they tend to come back becasue rez
