User blog comment:O Raz3r O/My Ranking of the 12 UK Series/@comment-2118191-20180907141719

I don't know about Killertron 2, and I really question Aggrobot's effectiveness in the long run, but if their annihilator performances in Extreme 1 were anything to go by, Arnold A. and Spirit of Knightmare would have made for some enjoyable fights with both showing high aggression. I could see both potentially making a heat final if the draw was kind to them.

I think the main issue with Series 5's dreadful newcomers is, well, the weight increase. This was the series that went from 80kg to 100kg, so effectively people weren't sure exactly what to really do. With the previous series, you at least had a rough idea, but here it was effectively starting again from scratch. When the format changes suddenly, even just subtly, certain robots can and will struggle.
