They do, trends are things that can't be ignored and the trend regarding Bioware's handling of retcons speaks for itself.
Do they don't, no it doesn't. This is a new creative team and a new game. Get over it.
It does back up my claim when they'd risk anything it means anything including economic collapse.
OK, so they would risk anything, but not for a plan B? That makes zero sense. You're applying selective logic to affirm your hiffy fit-induced nonsense.
Bioware intended for the crucible to be the only way to stop the reapers, they never considered a back up plan when they made ME3. There's also the fact the council did nothing during ME2 with regards to the reapers.
First of all, an Ark does nothing to stop the Reapers so you're not even making sense. Second, you're assuming the Council make this vessel.
An ark will also be just as risky since they never tested that it'll be capable of intergalactic travel and they be no one to save them if they get into trouble.
That's not an argument against making an Ark. That's an argument for having multiple solutions to the Reaper problem.
The crucible project and the war effort are taking a huge toll on the galaxies resources, they clearly cant afford another large scale project.
Says who? The quote provided only says they're utilizing resources from throughout explored space and are disregarding the economic impacts of the Crucible's construction. Nowhere in the game is it ever stated that the Crucible is taking every last resource and dollar to construct. In fact, the game tells and shows us otherwise. Cerberus has vast, seemingly endless resources. Your argument is based on nothing but empty conjecture.
They won't be testing if their ark ship will be able to stay function for a few centuries.
Yes they will. By launching it.
Considering the ship will be carrying the last numbers on many different species, the fact its going to be in FTL for a few centuries none-stop etc. Its clearly not going to be something that be drawn out in a months or years.
First of all, last numbers of many different species? Stop pulling BS out of your ass. Second, why would it take decades to design this ark? There's no logical justification for that assertion.
I'm not I'm just pointing the huge leaps of logic and and contrivances the whole ark concept relies on.
No, you're jumping to baseless conclusions about what the Ark is, who's on it, when it was built, how it has to be built, why it was built, etc. You have no facts or logic to support this BS you're spewing.
