With the unveil of Turbine's pricing plan for players who fail to "pre-order" the Isengard expansion, the model feels more like a threat than a bargain.
Under pre-order pricing, $30 gets you the solo content, the (single) raid, and the 3 single group instances (to be released later), along with some pre-order bonuses of various value.
Under the Turbine Point pricing, a $30 Turbine Point bundle on "double bonus sale" (one of the best sale exchange rates, comes around every other month or so) will buy only the solo content. If you want the raid and the instances too, you're going to have to wait for the double bonus sale and drop $50 (which will leave you with about 900 TP left over). There may eventually be discount bundles or sales that increase the number of "leftover" points players have after unlocking the expansion, but I suspect that the minimum real money pricetag of a bundle large enough to get the expansion will likely remain around the $30 range.
Unlike the game's low level content, it does not appear that there will be an option to purchase individual zones worth of content for smaller amounts of money - players will be forced to purchase all three zones at once for $30, or attempt to grind out 10 additional levels using unfinished content from previous expansions and scaling content like skirmishes. (One wonders in hindsight if the decision to increase the level cap from by 10 levels to 75, increased from the originally announced 70, was intended primarily to make the latter option less attractive.)
How to respond?
The irony of the situation is that the hypothetical $30 is not a terrible deal - that would represent the only real money I would have spent on the game in possibly a three year period between when Mirkwood content dried up and whenever the next expansion hits, and the purchase would provide full access to the endgame if I ever wanted to pursue it. Unfortunately, Turbine's decision to use strong-arm tactics makes choosing to pay under these circumstances feel less like getting something I want and more like giving in to a blackmailer - buy now or you'll be sorry when we make you pay twice as much later.
At the end of the day, I'm strongly inclined to call Turbine's bluff. If I "win", I get to see the game's epic core story without paying Turbine a dime (or, alternately, the experience is sufficiently unenjoyable that I quit the game outright). If I "lose" I eventually end up paying the $30 for less stuff, but I probably wouldn't have used most of that stuff since I haven't done much with the access to instances I currently own from past LOTRO expansions.
If Isengard actually turns out to be worth the money, this high pressure sales pitch was unnecessary - place a fair price on the thing and I would probably have purchased it. Instead, Turbine has chosen to reinforce every negative stereotype of the non-subscription MMO model, and I'm none too keen to support them as a result.
