From what I've seen the actual park factors are not that severe for Aberdeen.
Sadly, the best source for those that I've found is behind the BA paywall.
Assuming his pitching stays at close to this level I don't see why he wouldn't opt out unless a team signed him to an extension that would be roughly equivalent to what he'd get if he opted out.
He can do better than 3/49 on the market.
I think we have two main things holding the team back from being players for a front line pitcher.
I think Elias is overly risk adverse and I think ownership isn't willing to take on much additional payroll.
NO ONE is arguing that he is simply on a heater.
Some of us think he's super good and on a heater.
Zero folks here are denying that he has the look of a very special player.
