"Spamming"?
I hate Dretches spamming my face whenever I leave my base.
->Being a noob, not knowing how to tackle a dretch, I'll camp behind turrets.
I hate being blasted by humans
->Therefore I wallwalk (unpredictably) to avoid being hit
I hate luci-spammers
->So I avoid them, go round the other way, or wait for 0 ammo.
Do excuse me for the rather outdated analogy that follows:
C&C: I hate Orcas, they should be banned. I mean, really, I have 30 light taknks, yet a dozen Orcas can take me out?
->Rocket launchers/SAM-sites...
C&C: Acres of Mammoths?
->20 Acres Riflemen.
As has been said throughout this post, features AND I'll even go so far as to say bugs/exploits too, are to be used to your advantage. Finding ways to counter these "tactics" is part of the game (enjoyment).
The game, giving Maras the ability to jump, noob placed, forward turrets and attack reactor is the SAME game that allows supressive fire, controlling of crucial paths. The only difference between the last examples being that the former is more pro-friendly (against noobs) whereas the latter is far more in favour of the noobs.
The poor human player, despite the "advantage" of luci spamming(or any other form of spamming for that matter) will be swiftly dealt with by a good opposing team.

Features, exploits, bugs, are not the same as modified clients (aimbots etc..) They are advantages/dissadvantages that we ALL face.
