E2 is wonderful, I use it for control systems because the numbpad doesn't feel natural to use when controlling something and it is a great improvement over E1 (I never understood it).
I do however hold people that can make something GOOD without major wire assistance, a good example of this is Saber15's VTOLs the only wire used is a adv pod controller for activating the thrusters, all the balancing has to be done by the player in the seat which does make for some fail pilots but is ultimately more fun to just fly in than some applyforce() fighter.
As for people just hateing on wiremod/phx: Think about it, how many people would still be playing gmod if all this wasn't made? If we still had a pure vanilla gmod? Things like Saber15's VTOLs wouldn't exist because we wouldn't have the weight tool or smartsnap! Gmod would die if we didn't have such addons. Nothing new or fresh would come and all the players would leave.
Hell look at TF2 Valve brings players back with the class updates! Many have left and retured because of new weapons and maps and in gmod this is present but tenfold because of the community!
I hope this changed some of your minds.
