The problem with reducing the wraith’s mobility with decoy is that using it in the middle of combat to get away wouldn’t work unless the wraith had already broken line of sight, as the hunter’s would probably still be hitting it and the invisibility would be even more worthless against upper tier teams who would already be looking for the decoy activation animation.
I know its unpopular but I’m still in the camp that decoy should cost armor/health to use, with the cost refunded to the wraith minus however much damage the hunters did to it. This is ONLY if the wraith gets to keep the decoy’s ability to do damage as well as benefit from supernova and the ‘combat’ status attacking the decoy grants.
However the main thing I think is the problem with wraith is the primary difference it has against the other two monsters and that is the amazing evasion skills it has from the start. What I mean here is that you can force the other two monsters to fight if you dome them at stage 1 or 2 when the fight is in the hunter’s favor, but with a wraith, doming it is just the start of a second hunt because not only is the wraith built for hiding, its built for mobility. It comes down to the skill cap for beating a wraith is much much higher than for playing the wraith. I’m not saying a poor wraith can beat a good team, just that a mediocre one can evade decent hunters long enough that every fight will be in its favor and on its terms.
I’m not sure how best to deal with this either, but having a monster that can very easily avoid Stage 1 combat automatically shifts the fights to stage 2 or 3 and in the wraith’s favor. It would be very interesting to see the data of what stage most wraiths lose at. In my experience the wraiths we beat either were very new to the monster and fell in the first couple of domes, or died at the relay because they stayed in the fight too long.
The main thing I want to know is does attacking the decoy grant the wraith the combat stamina boost, because that is an advantage the wraith does not need. I ask this since I’ve seen it mentioned that attacking the decoy will pause the timer.
