Surround an outpost or a tp with heavy mechs shoulder to shoulder and not allow anyone to leave/pass.

It could bring a lot to gameplay: Griefers could block alpha TP with 10 Scarabs and I would sneak under them with my light EW

hmm, what advantages could it have to prevent several bots staying in the exact same spot.

have you ever read the argument about "superiour numbers will never be beaten" ? Can someone imagine how much difference it would make with all those robots blocking each other movement pathes? Especially if bigger bots need mroe space then smaller ones?

i know it would be the horror for garg to make the autopilot work under such conditions, or followbots
i know you all prefer twitch-independant mechanics like Interference and limitations on when follow command works.

in case of NPCs, you also prefer to cramp 50 bots on 4 tiles and let them explode, do you?

+1 to stranger danger.

Games I've noticed with collision have mechanics whereby each player involved in a colission 'moves' to some degree. So if you line players up in the theoretical block-terminal-circle-grief those players are not wall units. They move when collided into.

Actual OP question does not appear to be about "though shalt not pass" but about when you do pass is there damage to one or both bots? how is that calculated? and how long will it take someone to mastermind an out-of-box advantage that everyone cries is an exploit? 

But why even talk about this? I thought the Devs made fundamental decision long ago not to include collision mechanics.

I have an idea: lets wait for some *** forum whine where 1 or 2 or 3 people piss and moan about x and Devs can introduce Collision Mechanics to fix x and break a b c d e f g h i j k l m n o p.

to many mechanics are "only beta/gamma" to be good for the game. it either works for the whole game, or it doesn't at all.
there is not enough DEV power to develop two games in one. not even multi-million-dollar DEV studios are able to that stunt   (aka Red5)

DEVs also made many fundamental decisions long time ago, that doesn't mean that at one time they can reevaluate those decisions.

well, the only thing that any1 ever mentioned about it beeing bad, was blocking access to a teleporter or station with lots of robots on alpha where you cannot just shoot the blocking bots or place a plasmabomb on their feet.

so, why not bringing up this topic?
thats more interesting for me then who shot first between cir and joke
