Firstly, I would like to start off by saying this is the worst Call of Duty ever made and Raven Software should never be allowed develop the MP series again.
There is so much wrong with this game out of the box both from a casual gaming perspective to that of a competitive player.
I'm posting here on behalf of eSports and will try explain what needs to be changed below. The amount of work put in by Treyarch to revolutionise competitive COD cannot and should not be destroyed by Infinity Ward and Raven Software.
1. Hit detection - Your net code is terrible. When you die in-game it is instantaneous and feels/looks exactly like you were dropped in 1 bullet and 1 bullet only. From the kill-cam you can clearly see that the enemy who killed you done so in 4 bullets or thereabouts. It seems as though the game is accounting for your death before the bullets even connect in real-time. It's quite possible this is an engine problem but it's something that irks me.
2. Health - Why am i playing hardcore mode with radar on in core? Seriously. It seems like no matter what range i'm constantly getting dropped immediately. This is not competitive by any means and i'll explain why.
Given a 30 bullet clip and the fact that it takes 2 bullets to kill means that you only have to hit 6% of the entire clip to kill someone. I believe this is a terrible implementation as it does in no way, shape, or form account for gunskill.
E.g. Step 1: I run through a hallway and there is an enemy sitting in a corner.
Step 2: He begins to fire and misses his first 28 bullets before starting to shoot on target.
Step 3: I begin to fire as he has 2 bullets remaining.
Step 4: My bullets start to register immediately as my aim is far superior.
Step 5: I die as he was in fire mode even though he only hit 2/30 bullets.
Does this not set off alarm bells in your head as a developer? There is no skill-gap at present in this game because the health is so low.
I done some health tests on System Link (LAN) and found that double the current health is slightly too much but feel the addition of a 1.5 times the current health as a standard would allow this game play at a level that ensures 9/10 the player with superior gun skill, hand-eye co-ordination, and reflexes wins the gunfight. Bare in mind that if the health is increased the grenade damage will have to increase proportionally. Just use common sense.
3. Maps - Dear, oh dear, where to begin. They are far too big, depressing, and promote corner camping. I'm quite surprised that IW allowed Ravensoft make the MP maps after the reviews the Black Ops 1 DLC got. The game needs smaller maps. Take Firing Range, Summit, Raid, Standoff, Slums, Bootleg, and Hardhat as prime examples and get to work.
Designing MP maps is not a difficult task, so I really don't see the problem.
4. Modes - From a competitive standpoint the modes do not work. A lot of this stems from the health level and also due to the complete cluster that is the map design. Treyarch showed exactly why both CTF and HP were in the game and you removed them. Why?. Who knows. I just get the impression that anything positive that Treyarch adds is automatically removed. Completely baffles me.
Add Hardpoint and CTF. eSports needs it from both a spectator, codcaster, and player perspective.
5. Codcaster - For all that is good and holy please add codcaster. It completely changed eSports commentary in Black Ops 2 and what happened? You removed it once again. Stop being so egotistical and accept when another developer gets something right. You don't see Treyarch removing things you do right, so why do you do it? Set your ego aside and work at making this game better with every passing year.
6. Private match settings - Take a close look at those available in Black Ops 2 and do exactly that. No shortcuts, no ifs, no buts. Just do it.
These are very simple things you can fix if you want to. The key word being WANT. eSports is counting on you to remedy these huge problems because if you fail to implement the above you will have took a big 'poop' on all the work done by Treyarch and the huge influx of eSports fans they brought.
Disgruntled but hopeful competitive Call of Duty player.
PS: Please don't let eSports die. We beg you.
