You newbs, we all know the only real OP idea is Espionage... *covers from the rotten tomatoes*

Offencive is good nothing more, without high morale and high traditions its useless, actually 2 ideas of defencive do almost the same as full bar of offencive.
The morale bonus from Defensive is better than anything you get from Offensive in terms of actually winning battles.
But maybe the title wasn´t right... what I should have said was, Is there any reason why not get it as first NI.
There's also though the Defensive Idea's. 25% morale bonus (huge early)...
Nobody said to fill out the entire idea tree before going back to tech.Because taking any military idea as first idea is asking to lag in military tech, which is often a death sentence.
Millitary ideas 1st are junk. One out of diplomatic/exploration/expansion or even religious (if in a weak tech group) are better sells. In single player exploration is absolutely brutally OP right now, because it opens up conquest cycling out of AE instantly.
Unless you're sitting on a 6 military monarch+heir combo, there is no reason to get military first. 90% of the time sacking your diplo tech in exchange for a diplo idea, be it diplo or exploration or even naval is extremely beneficial. The benefits of the idea vastly outweigh the early benefits of diplo tech.Nobody said to fill out the entire idea tree before going back to tech.
I almost always take a military idea first (generally defensive. Offensive if I'm playing an op hyper-aggressive country like France/Ottos), grabbing any major early ideas (like morale, or the +1 leader shock), go back to tech, then put some more ideas, etc.
It's quite possible to have your first 2-3 ideas be all military, and not lag behind in tech, if you can manage it right (assuming you're not screwed by a bad monarch, but that's why I play with a mod that doesn't screw me over with stupid monarch stat luck).
+1.
Also, regardless of which group you take first, you should take a different type second. Alternate groups so as to maximize the purchasing power of your monarch points. Stacking 2-3 military groups in a row unnecessarily slows your idea progression. Of course, later in the game, once you've already filled out 3-4 groups (and your NIs), it's less important to alternate.
Me -- I almost always take Diplomatic first, both because I'm a diplomat junkie, and because I want to sprint through the first few levels of Admin and Mil tech as fast as possible. Offensive usually comes second. YMMV.
All 3 quality increasing ideas(offensive, defensive and quality) are strong, but strictly speaking, Offencive=>Defencive.
Army tradition actually give you better generals, for 1 idea, while offensive has, 3 ideas equal to this. You also get manpower recovery bonuses, from army tradition.
You save manpower by having better sieges, and decreased attrition.
10% discipline is not that huge of a boost.
You inflict more casualties on enemy by forcing longer sieges.
You get big boost to morale.
But I can see that forced march can be strong if you`re nation oriented at offence in rather small aeries, and you don`t need to siege a lot.
I don't think anyone is arguing that one single idea is better than a fully completed idea group. Defensive gives other valuable bonuses -- the morale is just the most obvious one, and I believe it's better than any single idea in the Offensive line.25% Morale is not better than 10% discipline and pips. Forced march is so good that it makes fighting good players with it impossible when they're large, unless you have it too.
The Offensive + Innovative + Quality trio is king IMO. A constant stream of high powered generals, increased discipline, better combat ability, and forced march = massive casualties and lots of stack wipes.
Especially since there's something about morale a lot of you are overlooking: you can compensate for lower morale by splitting your armies up and rotating them through a battle. Keep 2-3 armies close to each other, let your opponent attack first (to get defensive bonuses), and then march army #2 in. When they arrive, retreat army #1 and watch your morale bar jump as fresh soldiers take over. Repeat until victory.
