Not sure what advance stalwart is. What was wrong with the SA's proposed that were discussed? The only difference I had was perhaps on the cost with DC, but I don't see where that was that big a deal. Just asking.
That post above is all the long analysis, for those not willing to read it here is the short:
If you look only at this table:
it is crazy to imagine, argue, or defend that Temeraire, lacking the Flag 2 of both Lion and Alsace, lacking the range 3 seconds and true thirds of Alsace, lacking ER5 of Alsace, lacking the main boost of Alsace (due to ES granted) and having maybe 5.5 hull is somehow exactly between the two ships in cost. It is far closer to Lion than to Alsace--again 60-61 points.
Edit--and again--the chance to both gain back ER4 (Temeraire having only 1 hp of damage at the end of a turn) and being able to use ER4 rather than having a main target at range 3 or less is so small the argument is a red herring. (See the long argument for that analysis.)
I would not argue with a 61 point cost max, although I still feel this is probably high. I disagree that even 62 is warranted (which goes into my analysis). 63 is ludicrous.
Although its minor to me tertiary guns are a value over bristling with guns; I would much prefer to have the option to fire on the same target twice; to me it adds even more value to Alsace over Temeraire. Maybe not a points worth but at 61 your right on.
