Vermivorous is now possible farming in solo?

Continuing the discussion from Hot Fix / Update Information – Xbox One (Updated 1/25/2016):

can we realy do spawn a vermivorous in the “normal way” (varik evolution) and it is better than in the creature arena (round 2
) where an ultimate badass varik spawn every time?
Still search people OP8 to play on xbox one.
It’s better to farm alone than 2 player now?
