How would this add any kind of "depth"? If anything that would simplify it and boost the defenders, which isn't needed at all. OP pretending that there would be some "hard choice" or tradeoff in this whole thing is just false -it would be just another change that would support a winning side. Awful idea. No, it gives the choice and the opportunity an organised squad to come and re supply a dry t3 for example. This wouldnt be op since you still have to enter your own sieged fort which is probably surrounded by zergs. Also, you didnt bring this supply from the twisting nether, you had to take it from one of your other structures which is now more vulnerable. High risk / high rewards, see ?If your server suck well thats too bad (and actually anet fault aswell for giving no purpose to actually win rather than the ladder) and it's maybe time to tag up as a commander and teach people basic tactics you know. So yes, this would add depth to the gameplay, factually
