Its symbiotic in the sense HIVE was the origin and base to build on but very little, id say almost nothing, on the consumption side of things, about LEO or Splinterlands has to do with HIVE.

HIVE can act as that base layer but it will still continue to drop in MC until development of the base layer and securing it is pointless and waste of funds.
Being associated with Splinterlands or LEO will do nothing for it then.
