Blink strike operates around the same mechanics as a really fast assassin teleport. It is not something which makes them impervious to bullets. It's just a fast air sprint. That is your first lesson: keep shooting blink strikers. Never stop. The second thing to avoid blink strikers is familiarity of your radar AND having a properly prepared weapon beforehand. In crucible, blink strike users typically expect users to stay in a given spot for the shot. Ironic enough I've found a method of going underneath the strike and then jumping. The window for them to hit? Normally results in a miss of both shot and melee. The last thing? Avoid teleport areas. Keep to the doorways. If you see someone on radar? Let them come forward and pop them a new one as they come forward. Distance is your best friend with blinkers. Popular weapons against blink users? Hand cannons and pulse rifles. Specifically thorn, TLW, Bad Juju, and three little words with radar/3rd eye perk on it.
