I noticed a shift in the writing for 5.5. Some of the NPC's we've known for some time are suddenly using contractions such as I'll or don't when before it was I shall or do not.
For me the draw of this game was an older style of speech, it fit the world, it fits the characters. Urianger would not be himself without the Shakespearian. Most of the others however spoke a form of such. While not completely Shakespearian, it is mostly from the Elizabethan time period it would seem, in so far as my research has taken me. Some words are earlier periods, some later.
This new overuse of contractions however just feels lazy, like no care nor time was taken to properly write out the script per that character's speech pattern.
Some examples: "I shall remain here.", "I will bring"
to "I'll be reserving my strength."
Before: "I do not envy"
Now: "I don't seem."
Where they would say "Aye." is now "Yes."
Years of "Aye, I shall, I shan't, I will not, We have, etc" to a sudden "Yes, don't, I'll, I've. etc" All of this speaks of a lack of quality control and detail. To add to that the spoken portions of the character are familiar and in pattern, yet the non-vocalized are not.
The use of contractions prior seemed more a typo than the rule of thumb. Even so recently as 5.2 the writing was more or less consistent with how the characters spoke. Now... I near expect Urianger to begin using the words You in place of thee.
