First of all, i think bombing in lockdown isn't easy, but still people's in LD have weakness,weaknesses at LD players (Oftenly strikers) :
1. They dont care about fire vaporizer and haze bombs, although those 2 bombs is to help u to kill them or distract them with shock (they are aware with shock and freeze tho) when u have other side weapon inteads of bombs, But if you want to make them "Forced to use guns" , you must do it with freezing vaporizer ( or shock), even some ppl start gunning when we put any vaporizer, but freezing vaporizer is like "Sacred area" which nobody will enter in.Perfect for guardiang CP's
2. Not all people comes to health generators in maps, but the maps available with health generators are: Downtown, 2 health generator one in each side, Stadium, 3 health generator , one of them in the center (around up) and 2 in each team side in the South area which you must pass the fire traps in order to get in, And the last is mines, 1 health gen. in the center south.The first trick and the easiest in these health generators is to spam Toxic or fire vapor, not shock, Shock wont do lots of epic damage, except if u have a weapon with the damage around sealed sword.This could work if u use shard bomb , so when recon tries to get ot the health generator by sneaking, they can't do it because shards keep coming a lot surrounding the health gen.Or if you want put vortexes near health generator when they come too near, they'll get sucked all way in and just grab your sword and fight for it.
3.Never bomb alone.When you do full bombing or even you have side, still dont bomb alone.You must have a swordmaster nea you to protect each other, or a gunner, and both will work good.Maybe you think nobody will create a mini-team with you, Dont worry.You just need to find a crowded control point, or Team chat them to take a CP together.
4.Instead of never bomb alone, Double bombing could be good with different family type of bomb.Or do disco bombing, which bombing shards together, will do more lag and confuses your enemy with different shard color, such as normal damage with the elemental or with shadow.This TECHNIQUE works in clockworks (Disco bombing) if you are too bored to find good weapons
5.And the last, you should've knew from wiki, Bomb beats sword, sword beats gun, gun beats bomb.If you want to make that Mini-team (refer point 3) Then the perfect one s a sword striker people, which will help you alot.Double bombing sometimes made it suicide if ppl comes with pulsar, thats why before bombing in LD YOU SHOULD (not must) Have a pulsar or static capacitor (But im more sure you need pulsar more than it, dont it)And dont forget to play RT often for the quicksilvers, its perfect for LD, Anti shock for facing pulsar user(Especially bomber's weakness is shock because shock makes them cant put bombs because interrupted by the shock itself)and quicksilver too have anti piercing to face flourish-er or snarble barb user (In fact they are almost same).I know my technique all above this dont work so good, because i always get killed by pulsar because im actually not RT yet too, not even have 3 star armor yet, but other 3 star thingies is in my arsenal list.IF YOU know OTHER technique OF BOMBING in LD or want to fix my mistake up there, feel free, it wont cost you a dollar to give your opinion.Have a nice day :)
