How about a strong hull that can't back up.

The loud THUD THUD THUD this gun makes is great for disguising the sound of a mine dropping.

A bit off topic but generally, the best way is just to change the missions, and use your mines, and powerups. Find maps where you can join the winning team. Or of course you can just equip a dictator and memorize all gold box locations. It's hard though.

Dictator is awesome, it's so massive. I love climbing onto my opponents and dropping a mine on them. Turning a short range gun around and driving backwards gives better range.

My favourite thing to do is just base camp in Noise with another Isida and sit on flag while everyone else attacks. Nothing gets passed us. Once had 5 Isidas sitting in the base. The other team pretty much gave up towards the end. I think they should double the range of Isida, let it shoot through walls, make the beam jump from enemy to enemy damaging them all, and do self healing when you heal other tanks. That, in my opinion, would create a very balanced game.
