I always felt Merlin is a bit overpriced for what it does.
It should be about 500 metal cheaper.
Also I want it to have little lasers on the sides because it keeps dying to skirmishers because I couldn't be bothered to protect it properly.
Also, what would be cool would be a cloak function so that it can sneak around and blow stuff up as a surprise. LOL it will be funny to blow up a comm that never saw it coming. To make and mutate Iris takes too long.
That's in addition to the shields earlier suggested by Oflameo.
(satire ^ In case somebody takes me seriously ;) )
