Nope! You just need to push more on maps like ingress - I saw often you'd get chip on the player your side, then you'd riflejump back and take the one health pack in base, often waiting for the next hp pack to spawn. This is a bad tactic, because your enemy can easily push and kill you if you are low. If you die in your base, your enemy will be close enough into your base to riflejump in and take the flag.
However, if you're low, you should push, even if there are no health packs about. If you die far away from your base, you can at least respawn in time for your enemy's counter-attack, meaning you have another chance to kill the attacker - but this time you'll have spawned so will be 100hp.
One more thing on aqueous: we were ahead on flags, but still you pushed far out of your side. Your side was left, meaning people can either come from long side (the ladder way) or tunnel (the stairs way). If you pushed, it meant that someone could sneak past the other side and get back into base. Your tactic of pushing would have worked, except Jason was camping heavily in their base - and he killed you. This leaves the entire left side vulnerable. Basically all I'm saying is; try and be more aware of your surroundings - if you know we're winning on flags we have no incentive to push, especially when they're camping so hard.
Very minor faults, but overall you did well - I'm also very pleased you were able to frag so well - really you didn't play badly at all.
If it was TDM, you have the right idea, really! I used to do this in CTF like you all the time as well btw! It's a nice tactic for accumulating frags, and on maps where flags are rarely scored (such as depot), it's the way to go. Nice job anyway, I was impressed you were able to hold your frags even though you lagged.
