With a ground up rebuild of pets announced in the balance changes - along with a complete redesign of the mez pet line into a utility pet line, it may be worth floating the idea again, of MPs being able to choose which combination of pets they can cast.
The idea is that an MP wouldn't be restricted to having one of each pets - but instead could choose any combination of pets up to a maximum of three pets. So an MP could sacrifice healing and defence by casting 3 attack pets - or they could focus more on healing by choosing 2 heal pets and a Utility pet that healed nano perhaps... or whatever combination.
This would enable MPs to tailor their contribution better as a 'jack-of-all-trades' profession. In raids, having 2 or 3 heal pets could make their contribution more real. In teams with little crowd control, going over to multiple mez/utility pets would be useful. And in normal teams, the ability to go all out DPS would give MPs a more clear contribution.
In the past, this idea hasn't really held water very well. In theory, it's a self-balancing idea... but in reality, with pets in the past and present, nearly all MPs would end up casting 3 attack pets all the time. But with all of the pets being completely revisited, there's an opportunity to implement such an idea in a more balanced way.
With the new 'Utility Pets' and the potential for several different and more useful effects being given to that line, there would certainly be more of a real trade-off involved in not casting them. Suggested ideas for utitlity pets like short-duration snares, nano heals, blinds, NR debuffs etc would make losing such a pet for an attack pet a real trade-off.
With Heal pets being rebalanced, the hope would certainly be that their healing levels would make them more compelling as a trade-off too.
With both other pet professions already having the ability to have more than one atack pet without trading off defence, there's less of a rationale that having multiple attack pets would be unbalanced in some way - especially when the MP would have to trade off their heal/defence pets.
Going over to such a new system at the time that the pets are all rebuilt, offers the chance to revitalise MP team contribution and flexibility while managing balance where necessary through the stats/effects on the new pets.
