Excellent thread, thank you.
You should change the first post, the teeth pool resets every 24 hours with 1 tooth (as of early August patch).
It still glitches sometimes and shows zero when it resets, but it will award you a tooth if you beat the first barrier hive. I think it glitches when the timer resets; the pool starts at zero unless you leave/come back, but the tooth is there and will be awarded.
Thoughts:
The 5% damage boost made a noticeable difference in solo games. Magnum shot to armor will kill when it wouldn't before. (playing as tank; in solo, only one skill point is required to make it 1 stab kill on scouts).
Sentry armor is amazing. Maybe because i play solo, but 1 scout will kill a sentry quickly. A rhino will kill it real quickly. An armored sentry will kill a rhino that is trying to kill it. That's a huge difference. It lasts 4-5 times as long while being abused for only 5 teeth. How is that not 5/5?
Start with extra 1000: Compare: start with key means 40 points for a 1000 to 3000 point gun. For half the teeth (20), you get a guaranteed 1000 at start. That still isn't amazing, but if you are the scrub who isn't running sentry guns, that 4th guy not racking up the points, this would be a real boon. I'm not hyping it, just saying it isn't so bad.
Edit: (i use pistols only/magnum often, so) fyi, the improved incendiary ammo will kill in about a second or two from a single shot, which is much better than it used to be. However, the upgraded Armor-piercing did not show as great an improvement. (grill had these properly rated, i was just commenting).
The Magnum ACOG attachment should be rated 0/5, as it simply handicaps you if you use it. It really sucks.
Edit: i hate to be that guy, but i am that guy; why have a 3 point system to 5 points? Why not 1/3, 2/3, 3/3, instead of 1/5, 2/5, 3/5 (ignoring the one 0/5 of fecetiousness)?
Also, last time i played (second map) the Vulture was garbage, i have to assume that it has been buffed some (like it was in Safeguard)?
Flaming stowed shield 'farming': if you want to try something silly yet boring, you can 'farm' with the shield (needs flaming stowed upgrade); go to casual, upgrade to at least a 20 point shield (25 pretty much guarantees enough points), find a corner to sit in with your back to the craptids, replace your shield when destroyed. It will earn back the 700 that you pay for it each time. A good spot is the hummer (vehicle) on it's side to the left of the first poc hive, by the guardrail. After 300 boring scout suicides, you get a tooth. Edit: a better spot was standing on the railing by the turret by the lone hive of the right side of the road in the motel area; this is so easy that i did other stuff and just had to flip up a new shield when she started taking damage when her shield ran out. Otherwise, i wad barely paying attention. So after a bit of set up, it barely needs to be interacted with.
Other farm: (you'll get more for playing/winning on regular, but sometimes you just need a tooth or 2); go casual so any scout dies in 1 stab. Get sentry at least 2 points, up to maxed out, but never place 2 as they will waste points. But maxing it out stops it from overheating often. What i usually do: get 2-4 points in sg, put 2 in magnum for 9 shots/faster move. Set the sentry at poc start, on the road way back by the white barrel. Then stand on the first hive, kill most yourself, your sentry gun will do little work, last quite a while and protect you. The scouts will rarely try to get the sentry gun. Easy farming.
The '2 hive' solution: this needs only 2 hives beat for a faster farm; put 4 skill points in portable turret, go up to the lone hive on the right side of the road, go up the steps to the mounted turret. Set up in the back corner, facing the entrance and bore yourself some teeth. For a slightly more fun version; put a fifth tooth (if you have 'start with a skill point') in ims (you'll survive without ims if you don't have it), set up in the farthest back corner of start (by the guardrail). Drop ims, set up portable turret and play shooting gallery. You should aquire enough points to keep buying the turret and placing occasional ims'.
