I have to say I actually do LIKE the Combat Training mode. For many reasons:
I have purchased ALL three of the DLC map packs for Black Ops but never get a chance to play them in any of the online multiplayer matches. They never come up maybe time one out of ever 30-40 games i try. Unlike how WaW was just the opposite when i DO NOT have any of the addon maps for WaW, it was impossible to find any games to get into that was for the stock maps ... so thats why i bought all three MAP packs for Blackops so i can play more different levels online. and yet it wont bring them up. JUST only stock levels.... how ironic is that?!! So playing Combat Mode at least lets me enjoy the DLC map packs i bought.. so it at least I am getting my moneys worth out of them!.
Anoher reason I like the Combat Mode, is that I can choose any MAP i want to play and practice that map over and over again anytime i want to get better at it. Where as the multiplayer online you DO NOT get the choice of what level you want to play. Hence the first reason WHY i like the combat training! (see above^^)
Combat mode also allows me to control HOW many characters on a team . Where for example like NUKETOWN, 6 on 6 in a small level like that is total MAYHEM.. dont get me wrong it IS STILL FUN for that purpose. But i think it is MORE fun when your playing ONE on ONE (of course ONLINE with HUMANS not the bots). It is MORE strategic then being just total Mayhem!.... But the problem is no one wants to play one on one! SO The combat mode is good for that purpose too! OF course you can change skill levels of the BOTS but thats still NOT like REAL people.. cause they are either REALLY BAD or TWO DARN GOOD where one shot from across the map kills you instantly hehehe SO it is a matter of WHO gets the first shot off hehe!! SO i know NO WIN situtation there hehe!
And Since Combat MODE is much easier to get higher ranks faster, that allows you to unlock ALL the weapons and perks faster and practice with them and get the best CLASS set you are best comfortable with. OF course they do not carry them stats over to the actual Mutliplayer mode, but at least you know what to try to work for when you do play MP mode!
I hope they DO put the COMBAT TRAINING mode in the MW3. but i dont think they will as MW1 and MW2 doesnt have it. So why would MW3? Just cause BlackOps has it .. doesnt mean they will put it in the MW3! It isnt the same series. BlackOps isnt Modern Warefare! heheh! Sounds logical! I still hope they do though as i already have it PREORDERED!! :O)
