There are a lot of firsts in World of Warcraft. Some firsts are great -- our first level, first mount, first dungeon, and first raid. Then we have our horrible, cry-ourselves-to-sleep-while-hugging-our-teddy-bear firsts -- our first death, first wipe, our first night of wipes ... We always remember these firsts. They're permanently set in our mind (much like Magni is permanently set in Old Ironfoge, may he rest in peace).
Finally, we remember our first patch day. This first could fit in either category.
My first patch day was catastrophic. All of a sudden, my talent tree was different, my DPS was garbage (well, worse than it was before), and everyone was "LFM for Ulduar." I was lost, confused, and scared -- yet it was the first day I knew I loved the ever-changing World of Warcraft. Patches provide an always-evolving universe, and I love it.
Do you remember your first patch day? What patch was it? Was your first patch a good or a bad memory?
