Is that a specific set you are referring to? I feel they've made great strides. When the Vikings came out I also grabbed a Zulu and Ancient Germans set. I found the Vikings easier to put together, and better proportioned than the previous sets.
I had a chat with a friend in the mini making biz some time back and he opined that WF would be the biggest winners amongst the current crop of plastics manufacturers. Cheaper than Perry, Victrix and Warlord and their sculpting was constantly improving.
Seems he was wrong on the second count. Welcome to the future..... it's 1985 but this time in hard plastic.
