Add Tier Checking!
I noticed that GSA has one major flaw when it comes to checking tiers, for example:
Say you have 4 tiers and lets say one of your tier 1 links gets deleted by an administrator. Since GSA dose not check to see if a previous tier is valid, it will be building links to a dead tier. Meaning, tier 2-4 will be powering up a tier 1 link that is no longer valid and this is a huge waste of time.
To combat this, I think GSA should have an option were you can enable tier checking, so basically if 1 tier dies, the tiers under it will get removed.
For example:
You have 4 tiers, lets say one of your tier 2 link gets removed, the tier 3-4 (or how ever many tiers) links that was pointing to that particular tier 2 link should also get removed. Same thing for tier 3 links that was removed etc... basically, if the link that gsa was pointing to is no longer in the verified links list in the project that its building links for (like if you set gsa to build links to another campaign to create a tier structure), all the links under it should also be deleted.
It only makes sense to do this because if not your link building efforts will be slowed down traitorously do to the fact that you building backlinklinks to links that point to a dead end and not your money site which in tern takes you much longer to rank for a keyword.

watch his series
then you hit verify and delete those links that are gone!
You can subtract the URLs from the tier above from the Link URLs of the tier you want to check, leaving you with the items which point to nothing. It demands a lot of exporting and copy/paste from SB, SER and Excel though.
