Twisted Treelane: bots or trolls?

OKay fool on me if I overheard some unpdate or so, but I just had the most strange plays on the 3 vs 3 map.

Starting a normal game with free pick in 3 vs 3, all other five teamplayers chose the same summoner spells ( ) and didn't purchased anything (or anything smart) during the game. Everyone just ran into the towers to get killed, and even when I attacked them (first game with Kat , second with Akali ) they just ignored me and died.

In my second game at least one of the enemies behaved normal (bought stuff and fought me).

So did I just overheard the latest update making the Twisted Treelane into a place for bots or trolls or what the hell was going on? (I reported all the strange players, though they never entered the statistic chat at the end of the game)
