Gotcha, you raise some valid points. Skill swapping will present cascading problems, but giving the engineer so many good skills, while the soldier has so few is a core balance issue. It's one of those things that if changed, require many other things to be changed as well. Even simply buffing the soldier doesn't make up for the fact they lack interesting abilities, and damage compared to other classes.
Thanks for the intelligent response as well, sincerely. I appreciate every post that doesn't boil down to immature one liners, like most forum posts.
Engineers who don't think turrets are effective simply don't know how to plant their turrets.
I'm sorry, but this is simply false. I am not some newbie who has never played games before, I have spent my fair share gaming and I have played numerous games that have place able turrets. I fully understand the most effective methods to place turrets, but unfortunately due to their feeble health, and sluggish tracking, turrets are not able to effectively kill targets. This is especially obvious with experienced human players, whom understand how to effectively disable them with a few shots from cover, or a single grenade. In fact, I have yet to be killed by an enemy turret, as many others have said. I'm fairly sure I have been killed by nearly every ability in the game, from sticky bombs, to Molotovs, to mines, but never being killed by a turret says something about their combat effectiveness.
If you put one in the right spot, you can basically shut down the attacking team's objective until the turret is disabled.
I have never seen a single turret shut down the enemy team for any amount of time. At best, turrets are brief stumbling stone, such that any more than a single person can easily overcome them. Because turrets are so weak, when focused on they go down quicker than human players because of their static placement. The only suitable role I have found for turrets is to place them away from where combat will take place. So that they can occasionally fire at enemies to soften them up for myself. The turret shouldn't require me to actively help it. I don't put my mines down and then hover over them so they won't get easily destroyed by a single passing enemy. I put them down in the appropriate spot and they do their job just fine without me.
When you have a whole team of engineers planting turrets and mines in the proper places, it's pretty much impossible for the attacking team to progress the objective unless they have EMP grenades.
Again, any mix of classes using any mix of team work can shut down the other team, a team of engineers is not an exception. You could replace the same situation with a team of operative users skilled in placing caltrops and sticky bombs. The point however, is regarding the cost of a turret in a build, and their lack of effectiveness versus other single point skills. If turrets are supposed to be weak, they should only cost 1 point to get the highest ranked turret. I shouldn't have to drop 3 points for each turret, only to have them be sub-par.
