If you're like me and the fonts are just too damn small, check out two files Iindie added to omnedatumoptimum.red/files/
The files you need are Fonts.xml and FontsREADME.xml. the README has iindie's instructions, the other is the file you download.
Put Fonts.xml in Secret World Legends\Data\GUI\Custom.
Go to Secret World Legends\Data\GUI\Default, and rename both Fonts.xml and Fonts.bxml to Fonts Backup and FontsB Backup.
Open Custom\Fonts.xml in a text editor - Notepad will do, Word is not nearly as good - and carefully change fonts as you see fit.
IMPORTANT: this is a file that talks to a computer. COMPUTERS ARE STUPID. Humans can forgive a missed bit of punctuation, and figure out what the sentence means anyway. Computers can't.
So if I want to change a line like:
Font name="3D_TEXT" face="PetitaMedium" size="26" weight="Medium" italic="No" antialias="Full"/>
I can only change the bits inside quote marks.
Don't change the font name - that's how the computer knows what this particular line is for: whether it's for the chat, or the flying text that tells you you glanced, or the names in the team window.
You can, however, change size, weight, and italic freely. Face, you need to be careful of - make sure you have the new font face installed.
