Generally my local meta doesn't emphasise superheavies very much. I'm That Guy with more money than sense and a tendency to shell out for the big stuff. but I'm a hobbiest more than a gamer, so I'm quite happy to leave the big stuff at home and bring infantry and light armour forces to table.
Titans take effort to transport :P
The usual convention in local meta is that superheavies require both players to agree to them, same with fliers. nobody likes to bring a list that flatly can't cope with what's arrayed against them.
