First, I'd like to say that it's good to see people that aren't taking advantage of plunder. Giving up those free coupons for the sake of others is pretty noble. On to what I feel about the system. My biggest gripe is that there literally is no chance for most, if any, convoy-er's (is that even a word? lol) to defend themselves. Unless you're in a server where the top players aren't insanely stronger than the rest, you can't do anything. I have never faced someone with less than 45k power. I'm the second or third (can't remember) strongest in my group with 25k and the strongest has 27k.
I can't ask for help because there's no sense in both teams getting slaughtered. They don't even get much of a penalty for being rogue either considering they can stay in their base or be in a group the whole time without ever being attacked. On top of them not losing anything besides coins. Considering majority of the top players pay anyway, I doubt coins are anything for them to worry about. I'd much rather have a choice to do the mission without getting plundered for 15 or be able to take my chances of getting mopped across the floor by someone with 56k power.
Also, if even the top players can see how broken the system is.....how did this not cross minds before release? Regardless, that's the only real issue I have with 2.0 so far. I still enjoy the game outside of convoy. Except for arena, I just stopped because of how long it takes.
