Mythic Trickster - Class Mimic

[RanisTheSlayer]

I'm running Wrath of the Righteous and one of my players is planning on taking Class Mimic, the 6th tier ability in Trickster, and reads as follows:

Class Mimic (Su): The abilities of your allies are available to you with a touch. As a standard action, you can expend one use of mythic power and touch a willing creature to copy one of that creature's class features. You gain the use of this class feature for 10 minutes per tier, using the level of the creature touched as your level for any effects based on level. You can't copy an ability that has a limited number of uses per day (such as rage, smite evil, or spellcasting) or an ability that involves a companion (such as eidolon, hunter's bond, or nature bond). You can have only one use of this ability in effect at one time. If you use this ability again, any previous use immediately ends. You can't copy the same ability more than once per day.

Let's say he uses this on the party fighter to get access to his bonus combat feats. Will he copy the feats the fighter has selected, or get to select his own?

We had this same discussion with our group, we came to the conclusion that it's less broken if he picks his own. The reasoning was the fighter can change out feats and can build up to bigger feats while using his normal feats too so it could be the situation where the fighter chooses all the good feats as his bonus feats that now the rogue can use.

Also it's just easier to let him choose, and by raw it says you gain the ablitiy of a class of that level not those specific choices.
