This guy obviously doesn't play orks...
What differs from game to game? Sure, it can be the terrain, mission, dice rolls…etc, the list goes on. But, does your opponent differ? If not, have you noticed a change in play style? If not, have you thought about finding more opponents? (I realize that this option may not be available to everyone, keep reading.) What sets each of your opponents apart from each other? Sure, you can say their models, color scheme, mannerisms. Whatever the case may be, it comes down to one thing. Play Style.
Have you thought about how you play a game? I mean, really play. From before turn one; your play style has been developed. How? What lead you to choose the army you chose? Perhaps it was the aesthetics of the models in the army, or the fact you like to smash into your opponent in turn 2 and rip them apart in combat. However your army “came to you” so to speak, how you build it and play with it reflects your personal play style.
It is no secret that I have hobby ADD, in my 17 years doing this hobby, in 40k alone, I have at least owned (if not built, and sometimes played with.) 14 different armies! Sometimes more than one a year! So, in essence, that is why I finally decided on Orks. Once the new “5th Edition” Codex hit, I knew this was my army. Why? Well, it allowed me variety. Not in just unit terms, but in painting terms as well. Even if I did an all shooty Bad Moonz army, using black and yellow as the main colors, each ork would be slightly different. But I chose to do a united Waaagh recently to mix things up a bit more. Occasionally, I find the lure of building an all new Necron/Tyranid/Guard army tempting. But what could I do with them on the table that I couldn’t with Orks? Not much. Sure each army has strength and weaknesses, but overall there are multiple rolls I can play with my orks. They are an army that can “wear multiple hats.”
Which brings me back to play style, I like to switch up my lists, and try different things. (Perhaps this is why I have an ok track record with my orks.) Have you thought about altering your play style?
Play style encompasses so much more than lists and armies though. It comprises of tactics, mood, and personality.
Tactics - think about how you play. Do you like combat? Shooting? Large number of models? (Keep in mind that the more models you put on the board, the more you will have to put back into the case later. ß my only/biggest problems with my orks. Easily overlooked though.) Change your tactics. If you play a Imperial Guard gunline, have you ever thought of swarming the enemy in combat? Do a horde army. Sure, this isn’t the main strength of the Guard, but if the list is written well enough, and you use terrain to your advantage, etc…you can find it may actually be dependable.
