I wonder when the developers will finally realise that Contenders are an extremely limited type of content in terms of customisation. The only things you can change are the mask and the headgear. I could live with that if we were at least able to customise the colour scheme of the outfit itself.
And the only real new feature is the kill animations, which are now tied to Contenders.
But who's going to buy and upgrade this Contender? The players who are actually willing to spend money already fully upgraded Eve during the collaboration event, and they're unlikely to switch to this one.
