The point *you* are missing is that these combinations and effects are in the game already, and people can obtain about 90% of the effect in maybe 10-20 dice rolls. An exploit allowing people to spam G5 upgrades for the elusive last 10% makes a very small difference over and above what was already obtainable legitimately. This is why it's very very silly for you to be yelling "cheater" every time someone in a powerful ship defeats you. Legitimately obtained ships will be easily 80-90% as powerful as a "god rolled" ship. Pilot skill and knowledge of game mechanics are also critical; those last few percentage points make no difference when an opponent's skill outmatches your own.
That's not really true. The "normal" max you can get with for example DD's is around 135-136% (most "regular" PvP'ers I talk to are in that range for most their drives). Anything above that is a very good and very lucky roll. A God Roll that some of these players are sporting are at 140-142% afaik (I haven't heard of anyone above 142%). The difference in the two thrusters (let's say 136 vs 141), is "only" about 4% (6*100/136=4,41%), but the roll itself is 60% better! (6*100/36). So it's a matter of perspective.
Also, a ship with "all" God Rolls, will most likely be more than 4% better in some aspects of it, because the ones who accept a 136 DD, will also accept an "ok" roll on other modules.
The sum of all modules being 4+% better in one ship, unfortunately adds up to a bigger difference in total, because it affects TOT for
both parties, which mostly affects the outcome of a fight. If someone has 4% more damage, but can maintain higher TOT, less time being targeted, higher recharge of weapons and engines, etc etc, it adds up to a lot more than 10% more effective.
And then you add on the part about these players already being the best PvP'ers in the game (for the most part), because that is pretty much their only focus. The sum is pretty much "Ouch!" if you're on the receiving end.
