I am playing wardancers right now, let me do a summary
speed -> some tickers that are 1 tickers for normal attackers (system-space-system) are 2 tickers for a wardancer, so you find a few 1 tickers and a lot of 2 tickers. If you have some patience you can play wardancers as attacker resourcer, but definatly the speed is not attacker speed, in the way your target has 2 tics to rebuild ground in mpst of the times.
ops -> most of the current ops are informative (tho they lack IP and infil) not destructive. However they have a good magic bonus and 2 good spells you'll be using a lot: CPFF and Warcry.
Warcry is a good eztra because wardancer tends to be fat ressers and morale is often a issue.
attack -> this 70% permanent bonus plus No Fear (that you can easily cast) provides your empire with a permanent 80% att bonus without the need to research it.
research -> it is low but usefull in the long run. Wardancers are great resourcers wiht their science help, tho you'll have to research contruction bonus too. This low science bonus can look poor, but in the long run it helps wardancers not to be so lame.
definatly a good race to play resourcer, also good SS race because it has no negative income and you can research it. Now the problem is a few people choose wardancers because Paz or Quantum is much more useful as resourcers than a wardancer, and in the other side, a HC attacker will never pick wardancer bcause of the speed.
This leaves wardancer in the middle of two basic roles assigned to other more complete races for those purposes.
It does not fit the current setup in normal fams because of the current tactics in the game, but if people were able to re-define their thinkin' about a resourcer role then wardancers would have a chance. A resourcer dont have to be a defensive role and thats waht people should realise and start playing more offensive (Wardancers!!)
How to make Wardancers more popular??
You have to balance their stats to make them a usefull attacker, so people would have to choose between a custom or a wardancer to play att/res role (not HC!!). This means MORE speed.
My advice is to lessen research (from 20% to 0% bonus), lessen income (from 0% to -30%) and increase speed (from 60% to 100%) the way you have more 1 tickers in a war. Make them be the opposite to Quantam, their competitors, a barbarian attacking race not using science bonus at all. I'm sure there's a lot of people who'd play that role (still 0% research can give you a decent construction bonus in the long run).
Reducing income to minimum (-30%) would definatly cut their efficience as SSers, but whats the point of having a race for SSers anyway??
