Don’t worry I know the majority of players don’t agree with me on this so the likely hood of it happening is minimal.
However, my mind is stuck fast…
I personally don’t really like Dirty Bomb the way it is. I find it to be one of the most shallow FPS experiences out there and I try again and again to find the route of that problem in my mind and it almost always comes back to stuck fast metas. The very things you say facilitate and to some degree mean a Merc switch is important is the exact same things I see as the reason why there should be no Merc switch.
From my own personal experience, when a game lacks mechanical depth (something that DB lacks massively) a meta establishes very quickly and it becomes all about skill and very little about tactics and in some cases even team work. We see it in Tribes, Black Light, Firefall, Shootmania, TF2, CoD and Battlefield. Each objective will be worked out what the best option is with maybe the odd variation (ie, take a sniper maybe, try a redeye for the smoke or proxy vs bushwhacker) but the core will always remain the same because you have the option to take the “most effective” combo for each objective. Soon as you add 3 reserve Mercs (unless it was pick and ban with 1 of each merc across both teams) you end up being able to cover almost every objective with a optimal pick. Once the optimal picks are worked out there is no tactical depth… It switches into a skill / timing effort. Tactics get left at the door again.
You end up in a situation where only 2 or 3 teams in the whole game have the ability to play tactically because they are the only ones capable of breaking and advancing the meta.
I also believe you limit your competitive player base to the players that can play one or two mercs really well. Where with a full lock in system we could see players just really unable to play X merc at Y objective so decides to play Merc Z instead. All of a sudden we have a team running a Sparks because they could not handle the Aura on the EV objective.
Ahhh **** it, im rambling again…
Basically, I hope for a more balanced skill to tactical experience compared to what we have now, skill skill skill.
