No I don't. If you don't see the problem, good for you - that doesn't mean it isn't real, and "proving" it exists to you isn't anywhere on my priority list. It's a genuine problem, lots of people have seen it - as is borne out by the multiple threads reporting almost identical symptoms - and your opinion as to existence or otherwise will not affect BioWare's response.

Just because you haven't experienced it doesn't mean that this problem doesn't exist.

I think that stuff that you already researched to blue has only a 10% chance of learning a new schematic, not 20%. I'm at work though, so I can't double check that. Anyway, it might be worth double-checking the tooltip when you hover over the item before reverse-engineering it.

This has been a really noticeable change since the patch. For some classes, it's not really an issue, but if you rely on your companion for tanking/damage soaking it can be big trouble. Other than the possible increase in spike damage, I think that threat generation seems to be less reliable; even with Khem in threat-generation mode, my Lightning sorc seems to attrack a lot more grief than she used to, and I can't seem to shake that threat even if I'm not attacking. If I am getting hit by two silver enemies at once, the damage can quickly overwhelm my newly downgraded shield and healing abilities.
