Welcome to Librarium Online!
so last night I played a 1500p game against my Space Marine friend, ofcourse he got the first turn and because he have to deep strike his drop pod first turn he decided to go for my big gunz, he got a perfect hit and out comes a dreadnought with a flamer and just kills all my crew members, is there a way to be sure this can't happen?
Hey...somebody's gotta die......
Park your Big Gunz near terrain (preferably impassable/dangerous) and park a screen of grots next to them. Most people are hesitant to Deep Sttike into places where a single unlucky die roll can kill of the unit by Deep Strike mishap.
Revenant Moon Necrons: (W/L/D) 0/1/0 (6th edition: 13/2/2)(5th edition: 14/6/4)(3rd edition Codex: 16/4/7)
XIX Legion: (W/L/D) 0/0/0 (5th edition: 14/12/2)(5th edition Codex: 4/3/0)
Black Legion: (W/L/D) 1/0/0 (6th edition: 2/3/0)
Something Wicked... Reikwald Beastmen: (W/L/D) 10/4/1
Just laugh because he used his 100+ point unit to take on 60 points of grots.
All you can really do is either add a second unit of big gunz, and be prepared to take out that dread on your following turn, or to keep your big gunz in reserve. Of course, they won't be as effective that way (missing at least 2 shooting phases, possibly more), but it'll keep them alive longer.
"Any job worth doing, is worth doing with a powerklaw."
It's a grot's life. If someone start to shoot at them they will die. As an ork player you have to accept that you loose models. A lot of models. But still win big.
For special defence from drop pods: Often you can influence where your opponent will place his pods and what units he will hit first by how you deploy. Flamers in pods are nasty. Spread out a lot. This will limit the number of hits and you can fill up parts of the table you don't want him to land in.
If he got a lot of drop pods. You can try to go second and keep everything in reserve. Then he has to drop half of his pods withou knowing where you'll come in. Rendering them useless.
Every game is different. When facing drop pods, try the do not deploy trick or accept that they are going to land and take stuff out so try and deploy to plan for it.
Most of the games I have played with drop pods you will have a pretty good idea when you deploy where your opponent is likely to put things.
I tend to place a unit of lootas near my big gunz that way when something like that happens either the lootas or the guns have a chance of retaliation.
