My quick rant on light levels.
Reaching highest light fastest is a great thing, imo. We've had both sides multiple times and both times reaching 34 via Variks/Nightfall/Trials/IB thanks to Etheric Light, and today's scalable drops via faction packages/nightfall/PoE/Trials and Raid with 100% infusion, it's a beautiful thing.
You can concentrate on getting your perfect builds faster, playing with guns you can keep, and most importantly, concentrate on the part that's most fun for you while being at the most optimal light level value for all activities.
I understand some people, chasing highest light is fun. I don't find that fun at all. Pre April 12, I stopped at around 315-317 on all my chars because the work was too much and I have more fun just playing what's fun asap.
