Lets see if any of this helps.
1: This was dealt with MONTHS ago, so they can only stay on an enemy carrier for 90 seconds, then they are killed. As for spawnkilling at an airfield, well, we all hate it too. Tank reload time was recently shortened, so its much harder to get away now. If a plane is spawnkilling you, well, getting out of that requires a: the enemy plane is distraced by a teammate, which gets your teammate killed; or; b: you get up while theyre turning, drop your bomb, and try to down the spawnkiller. This takes some real skill, but ive seen you, your pretty good.
2: In practice mode, yes, the enemy has insanely agile and fast planes that you cant HOPE to kill in a turning fight. Same with those tanks. In multiplayer, its simply that theyve upgraded their planes more. Dont worry about it. Everyone deals with it, and lots of us that dont pay for credits (either out of lack of funds, or the principle of the thing) still deal with it. If theyre not in a plane with superior stats, then they dont carry a bomb. It makes you faster and more agile, but, you dont have a bomb. Thats the only downside except the lost accuracy from the extra sensitivity.
3: Yeah, the writings annoying. A tactic to deal with enemies clogging the screen with text is to shoot them down.
haha, jk. If theyre flying level. Go above them, and the text will spread out some. Much easier to kill them. If you mean the chat at the left, well, sorry, its part of the game. Lots of people love the social aspect of this game.
4: Immunity is a glitch. Z intended it to make it impossible to kill people on the runway, or kill newbies for a few seconds afterward. Sometimes it extends. It only happens on appel devices, but its annoying, huh? We all deal with it tho, so it kinda evens out. Theyve got an immune guy, you might have an immune guy. Its close-ish to fair.
5: Its either lag, or bullets they shot befor they died. My only advice: kill them sooner.
6: Another glitch, but this is partially ur fault. If your firing, and u move ur finger off of the button, the bullets become sporatic, not as regular. They beign to fire in pulses. Keep ur finger on the button, and it wont happen anymore.
7: There is no #7. Good luck, and I'll see you in the skies!
