You might have noticed I did not include Grey Knights in the above list of nerfed armies. To me and my way of thinking this was a perfectly written codex that has as close to perfect balance as you'll ever find from the development crew at Games Workshop. The thing is Grey Knights now require some actual modicum of skill to play competitively. They lost their OP-ness but also gained some quite nice points reductions for certain units such as their Librarians and the Dreadknights.
Grey Knights are truly a strong army when fielded using their Nemesis Strike Force detachment and allied with another Imperial army such Space Marines - this is how the game is intended to be played now like it or not. While Draigowing is a relic from the past, DraigoStar is extremely competitive and can beat any other army in the hands of an experienced competent player.
Give and TakeGW gives with one hand and takes with the other... We have all seen and experienced the OP-ness of the newer codices such as Admech, Eldar, Space Marines and Necrons. What was really good in sixth edition is even better now and I think we should except that for what it is rather try to impose our sense of how the game can or should be played.
Continuing on with this train of thought there is a general vib permeating the Internet that the new Tau codex will continue the neo OP trend - however anything could happen such as the Greater Good getting the Ork treatment. Tau are one of those armies that has always been very strong initially upon release but then wan over time as the game continues to progress. A good example is the effect upon Tau as a competitive army in 6th edition and what they have lost in 7th edition with the advent of Maelstrom missions and the refinement of what constitutes battle brothers in regards to allied choices... Tau-dar which once highly was vaunted as Ched-dar is now looked upon as nothing more than a limp biscuit... hurrr hurrr !
Some herald the release of the new Tau Lord of War choice (I.e., the Taunar) from Forgeworld as a true indicator that the greater good will continue to receive the royal OP treatment from GW. While the Taunar is indisputably very strong we should keep in mind that there is and always has been a general disconnect between Games Workshop and Forgeworld for whatever reason. Also keep in mind that for the points cost of one Taunar you can roughly field two bare bones Wraithknights.
We have all seen the picture of the new Surgetide which will probably be classed as a super heavy walker and it's truly a huge model towering over the likes of other Tau units such as the ever humble Fire Warriors. Ask yourself this one question - will it be viable to build a competitive Tau 1850 point army with a gargantuan monstrous creature and a super heavy walker ? I highly doubt it simply due to what will be the most likely points cost for the Surgetide. Wraightknights are competitive mainly because they are criminally under costed. So most likely you'll have to make a decision which of the two is best suited for those of you that like to play Tau.
What to do now and where do we go
This is a serious issue for armies such as Orks. Many of us were shocked when we saw new codex. Many of use expected a bit more and Orks require the use the use of at least two separate codices to build a semi decent army list. It seems that GW has finally got it right now with Khorne Deamonkin, Eldar, Necrons, and Space Marines - everything you need is in one codex again and I think this is a good move on their part.
A lot of players are using allies of convenience and Come the Apocalypse to supplement their army of choice and this seems to be the best route to building an army that can perform well on the tabletop. It is literally the age of the ally now. Interestingly enough the most buffed OP races such as eldar, Necrons don't really need any allies with their super amazing formations and detachments that provide yet even more awesome rules. While this may well be a marketing ploy I just have to say wow it really seems to be working well for them... and so we come back to our dear old friends the Tau - will the trend of uber OP-ness continue or come to an end ? What do you think ?
