Pro Titan TIP #1:

When the clover/cross bombs come out, have everyone besides the tank stand on one of the bombs at the end of the cross. e.g.

A__S___A
_X____X_
__X__X__
S__XX__S
__X__X__
_X____X_
A___S__A

A's are boms at the of of the cross and S's are safe spots. If everyone stands in an S then the chances are that titan will Landslide a Safe Spot causing people to move in a pinch and often times die to a bomb exploding.
So what you do is "BAIT" the landslide. The A's (end bombs on the cross) blow up last and titan landslides before they blow up. So if all the people in the group stand on an A, titan will landslide an A (a non safe spot) then you run into a Safe spot to avoid the landslide and not get hit by a bomb.

The cricle bombs are the same way, you just stand near the last bomb to go down and when he landslides that the first bomb will have exploded, so you run there.
