Some of the older members (old as in time on the forum, not just age), will remember when a Star Cannon was
cheaper and more than effective than it is now and was attached to an
average BS Guardian platform.
I could easily go on, with 'old' stats and values, but the nature of it is that my tourney legal 750 point army from 3rd ed (and most of 4th) is now about 1000points, my 1000pts army from 7th is about 1200pts in the new way.
If you want to play Eldar, there are some hangups. I see it in the following way, for 6th and 7th ed we had a points revolution, lower than ever costs on models and while the Star Cannon is a popular weapon to complain about, we have a great many choices, and with Shuriken weaponry rules, we can't complain too much.
Dire Avengers are
xpoints per model, better over-watch, faster on the ground, assault weapons that lay some smack when firing en masse, have access to the best transport in the game (which we can assault out of again). In addition, the Exarch weaponry allows for an invulnerable save.
If one looks at a base price and says this is x and this is y, Marines will win out all the time, however our bulk standard seriously kicks but. In a 1500point game, we are weaker than most, at 2000, we will be on par, and 2250 and over, we are the Lords of War. A Space Marine squad starts at about 65points for minimum size way up to just over 200 for a full 10 with heavy Weapon and Special Weapon.
The Support weapon is huge from having to pay 105 for three shadow weavers, to almost 100pts each. That's pretty steep, but as the rules say, once deployed, they are each separate units. So each Shadow Weaver is its own squad for all intent and purpose, but up to three on one Heavy Support slot. Consider the rules, and firing, three at the same squad or at three different targets, the Shadow Weavers are now the go to weapon rather than the 'lets avoid at all cost' weapon (I always used them).
I've been here, and GW will listen, but in theory, there is an Eldar Codex aeround the corner and the response will be "Wait for that, you will be suitably impressed".
I've been here before when it was
x points for a Shining Spear model (not the Exarch, just a Shining Spear), the plea fell on deaf ears. Then a revision or two later, everything I was told would never happen, occurred.
With current comments about Plastic vs Metal models (think Sisters), and with Orks costing way too much (as in currency per point) , there are other balances that are really more important.
You just have to wait, play the game you enjoy, and keep the faith.
Please avoid posting stats, even old ones, as it's against forum rule 1 - Iris.
