@Tee_Doff2369I said exactly what I meant to say.
"...What makes a class? Previously it was gun, gadgets and armour. Specialists can have any gun, any gadget and their armour tells you nothing about them..... "
What makes a class is the combat role it performs, which was in the name. Those roles can and will still exist within the game, but there is simply more freedom and variety within and between them.
"...like how do you encourage the use of ammo/medikits over more fun/solo oriented gadgets I e. RPGs?..."
Ah yes, the age old question of Battlefield (and team-building in general): How do we make inherently selfish individuals behave and perform as a team? I do not believe Specialists are going to influence this problem one way or another. Those players that enjoy and participate in the team aspects of the game will continue to do so, while others will not.
"...This removes a tactical element that I liked that they can't get back."
Target prioritization is important, no doubt. However simply knowing how to deal with an enemy at a glance (no matter the range, many times) is unrealistic and in my opinion, stale over time. I would argue that this is one of, if not the most important, points of weapon optics... I will agree in general that this point is a valid concern overall though, since I have not seen consistent draw distances (and only on one map) that make this reliable enough.
Lastly, yes the meta game will be a bit crazier in Battlefield 2042, I agree. Constant tweaking has been part of most Battlefield games though and my only real hope is that EA DICE have not bitten off more than they can (or want) to chew... we will see.
