So, Elite Specializations are pretty cool. They add a new specialization, new utility skills and a new weapon to a class.
But, the downside is the limitation that is having to use the new Specialization to be able to use the new weapon and utilities as well as going forward the specialization itself will become more notably limiting since you can't use multiple Elite Specializations together (Meaning that each new Elite Specialization still only has 2x the current 5 core Specializations to use alongside)
As such, I was wondering if core classes might ever be expanded upon? Given that such a thing would create more potential options to utilize. I.e. A new core weapon/Utility set could be utilized by any combination of Core Specializations as well as any Elite Specialization. While any new Core Specialization increases the pool of options that can be paired with an Elite Specialization (Whilst also making more combinations for 3x Core Specialization builds)
If necessary, you can continue to lock these additions behind Expansion content (Such as how Elite Specializations are unlocked), it's just it would be nice for new content to have more flexibility.
