I was messing around and tried Tommy's Matchbook with the Elemental Well mod 'Well of Life' and noticed it results in constant flashing and a lot sound effect as the shield breaks and is healed. It's not crazy rapid, more like 3-4 times a second. I know it's to be expected with the build gameplay, but visually it's very obstructive and it just in case wanted to let Bungie know in case it's dangerous for anyones health now or in the future. side note: the stasis heavy grenade launcher also flashes very bright when detonating near yourself compared to other elements.
