I've had a few opportunities to play Warhammer Online. I've tried a varities of archetypes and sides. I must say, I prefer to play Chaos as a Zealot. The Lord of Change, Tzeentch, holds my soul! Unfortunately for me, my beloved plays an Empire Bright Wizard. She channels the primal powers of fire for the Sigmar and the Emperor. A few things I like about Warhammer online; although it takes many tips from World of Warcraft, it doesn't do it in such a way that makes it feel like a clone; it feels like a completely separate game, albeit in the same genre. The professions in some cases is not exactly intuitive, Scavenging for example is hard to grasp how to salvage some of the wrecked items which (theoretically) can be repaired for use, but is very simple to see which enemies have extra loot that only Salvagers can acquire, but Cultivation is rather entertaining although more time-consuming. The seeds drop very frequently, and it is apparently the supply profession for alchemy, or chemistry, or whatever they call it, I dunno. More than that I haven't found trainers for, we'll see what's available in later portions, thus far Rank 5 is the limit of my accomplishments.
The UI would be my biggest complaint. Sometimes it feels very crowded and busy, with notifications sometimes occupying important parts of the screen. However, the ability to choose a defensive target is very nice, allowing simultaneous support through healing and buffing as well as continuing a stream of damaging abilities, which is useful for when you're with only one buddy. This came into sharp relief when I was working with some people I met online, three Marauders, the close-range damage class, were attacking groups of well-armed refugees. They were close to dying when I came along and managed to keep them alive long enough to dispatch the remaining few, so they invited me into their party. At first, they had difficulty with groups of enemies, engaging one or two at a time, but a few pushing through to attack me, who has fewer defensive capabilities. But later on we found a Chosen, the tank class for Chaos (tank = heavy armor, many abilities to keep the enemies focused on himself), and things went much easier, I'd keep him as a defensive target, keeping a steady stream of healing spells going on him while being able to use my offensive spells to weaken and chip away at the enemy, while the Marauders just went wild, and if one started getting low, I'd just switch defensive targets to heal them, while still keeping an eye on our Chosen friend. Quite successful.
My goal for this post was to make it easy for people to understand who don't have much of a background in video gaming. Feel free to ask for clarification. So that's all I can think of right now, I'll post more about my experience as an Imperial Warrior-Priest and also on my World of Warcraft guild's progression and my never-ending quest to get better and better gear.
