foreword: i wrote this really late at night and its supposed to be a pure joke, so please treat it as one :), i stole the idea from a post about healers in another game, and thought this would be humorous, so i took a shot.
Chapter 1. Combat
A) How should I spend my 9 points?
Well, you obviously need to spend 1 on gorge, so 8 to go. 1 for bile bomb, and 1 for web, 6 to go, question those and just stop reading. next you need adren and regen to be able to attempt to be useful, so 4 to go. now you can get celerity, if you want world domination you gotta be able to get places, after all. next comes focus, damage = overtake your opponents. 3 points to go, you can get scent of fear if you aren't wallhacking, it helps to know where to web up before the marines get there. 2 points left, you get carapace because living longer only hurts your opponents. the last point is your choice, deem it on the situation. i'd suggest cloaking, for reasons to come.
B) What about classic NS?
you're going to want adrenaline, regen, and focus. these allow you to recover from any stray bullets that may go your way (hey, people miss the onos sometimes.) and you can web up easily and spit.
Chapter 2: Levelling Up
So you finally hit level 2, and you're a gorge, or you just spent your 10 res and now are the pudgy one.
Betya think World Domination starts now, eh?
WRONG!
The next 4 or so levels will be really tough, but play it out. you are going to dominate the world, after all. if its classic ns, let the domination begin by dropping some dcs.
So you got your upgrades, and are happy, World Domination time?
WRONG!
World Domination won't start for a while, these things take time.
A) How do I get by?
basically you have to whore yourself out and try to steal kills or leach exp in exchange for some healspray. cloaking also helps, as you can leech better, but this is best for combat.
B) Should I drop ocs?
YES. more damage = more domination = more res = good.
Chaper 3: Knowing all
World domination requires you're a smart one, and can predict your opponents. SoF helps with this. knowing how to focus spit then healspray then spit again also comes in handy. following an onos in combat or something equally destructive for exp is good as well, dropping well setup ocs in classic can be dominating. at first you will die, often. a lot. but you'll learn from these deaths, and eventually becoming all knowing.
Chapter 4: Tic Tacs (or tactics, for you dominationless people)
Heres where the domination really prevails. to dominate you must learn various skills: focus spit then spray, web while in combat, and dancing around your ocs. keep your opponent webbed and he can't do anything against you but stare. also, remember to always S.K.I.P., suprise keeps it perfect. don't get caught off guard, or your dead meat. always have the upper hand, and you will dominate.
one opponent: web twice, spit, web, spit spray, web and so on till he dies. if its a HA, web it a few times and run like hell because you won't win alone unless he's hurt. jetpackers are your folly, as they think they have godmode but fall instantly to webs. if they have a grenade(launcher or hand) try to get them to waste the ammo then web them down and you win.
multiple opponents: world domination requires lots of work, you're going to have to web a lot here, and just healspray since it hits everyone in front of you. skill is what prevails here, and you'll need a lot of it.
Chapter 4: Cheating and Dirty Tricks
know how annoying web is? make sure you abuse it. a lot. always. put them on the floor where people won't see them and take control. setup trap areas, but change them every now and then.
a. you remember bile bomb? well you can web the marine guarding base and take down his armory. that'll get him really angry, loss of his amoury(spelling intended)
b. cloaking is like a free get away, remember to have a key bound to walk so you can avoid people while you regen, perhaps consider silence over celerity for this.
c. kill everything. level one, vanilla marine, friendly or not. they are worth something no matter what level you are. if you're level 10 in combat, kill them even more, just for the sheer domination, after all you're trying to dominate the world.
I know, World Domination sounds like a lot of work. IT IS, but if you find that a bit too daunting....perhaps you should try res whoring for onos?
