I'd argue that tier 2/3 are at a similar power level, as there are cases where a "Decent" craft will not outweigh set items in some cases; that being said, it is pretty easy to craft, simple shrinecrafting rules:
- You might not a pile of ideal shrines to try rolling perfect, but you probably have a bunch of other shrines; if this is the case, keep a few shrine charges available for blessing, and try to trade extras for shrines you need if you're able. You're looking for one decent craft to supersede your TU/runeword options.
- Aim for two or three specific good mods you absolutely need, and don't worry too much about the rolls necessarily. For example, this is what I got in like 2-3 shrines for a naginata by just aiming for decent damage, +skills, and a proc. No blessing either, just threw a bunch of extra trinity shrines at it:
It'd eventually get replaced by either the set naginata or a Frysturgard, but it does some damn good work otherwise for the 100-120 range, and you can jewel/mo in breakpoints/resists/stats easily enough. Filled with Jah runes, for reference.
The moral of the story is pick two (or 3 if you're greedy) good mods and roll for those specifically. You can always 'leapfrog' crafts too by incrementally shrinecrafting back and forth between items as you improve past each one.
