I use a tier 3 gun but it lets me put lots more armor on. This one is a glass cannon.

i do this but with a tier 5 in tier 2 xD for le trolls

I would argue that nobody should be banned for doing this, though. It's well within the game's designed mechanics, and isn't glitching or hacking at all. If that's a problem, fix the game, don't ban the players for simply doing what they are allowed, by the game, to do.

I have a small 10-block buggy with t3 armor and t4 plasma, things are exactly the same + it's even harder to hit

The problem doesn't go away at high tiers. Typically once you hit tier 8-9 you will start to get matched with people a tier or two higher than you which is a HUGE difference. 1 T10 craft can completely annihilate 3-4+ T8 crafts. lol

It's very common now to face players with T7 in T4. Looking thru the Robocraft forums (not the Steam ones) You can see some players are getting warnnings about this, some have been banned for "Up-tiering". Unfortunatly the game is still in too early of development for them to be able to do anything other than have volunteer mods issueing these warnings off nothing other than otehr players complaints.

It's almost in a players best interest to get into T5 as soon as possible, cause the T5 weapons can handle these up-tiered opponents easier than anything lower; and T8-10 is so expensive to repair, it's not really worth it for solo players to take the chance. Of cousre you get 3 or 4 player Platoon all working together with high-tech toys, you may as well kiss that match good-bye, and just inflict as much damage possible so the RP covers your own repairs.

Heat, it used to be Tier 4 tech in Tier 1, not sure if they changed it. I made this video after I made a rant on the forums about people bringing in high tier weapons to low tier games and 1-shotting people, and some people seemed to think this wasn't possible.

LOL, another player showing off how bad he is with a video! The Best part is it's T3 tech in T1? R U seriously not able to handle T3?

Yep, those evil tier4 rails, 1-shotting tier1 people all the time, better nerf the living daylights out of them (nevermind the fact that plasma of the same tier can do the exact same thing, times five...as show here)...very nice demonstration.

I did the same with Tier 3 Plasma Cannon, so I can have Tier 3 armored blocks as well.
