More events IMO make the game less bland. I don't believe it gets too deterministic unless there is no B option. What drives me nuts are the huge number of broken events that the game shipped with. For example, why should the player wait for the Crimean War events when all it will gain him are more potential enemies in Sardinia,France, Austria, or Prussia. Ideally the incentive would be that the Tsar of all Slavs event would only be born in 1853, but you can do it starting in 1835. AI Russia declares war on the Ottomans constantly, before and after this date, whether they won or lost. The Tsar of all Slavs event itself doesn't work right because it has triggers in 3 countries, Ottoman,Serbian, and Wallachian, none of which are ever allied to each other again after the first 10 years or so. Since you can't declare war on more than one civilized country at once (makes no sense), this event is all but impossible to accomplish, with the end result being that it and all of the Crimean events are useless. Same with the 2nd Oriental crisis, any Ottoman player should just DOW before they fire if you want to avoid French intervention.
Or how about forming Mughalistan ? The only way it can be done successfully is buying territory from the UK to get a border with trigger countries, since uncivilized can't DOW anyone who isn't their neighbor, and the UK won't surrender a single province even if you occupy all of India. End result, it never gets done. How about Italy ? Sardinia in the extremely unlikely event that it beats Austria and the Two Sicilies, will peace out before getting its overly complicated set of triggers, end result no Italy, ever. Germany ? It's far more likely to remain Prussia until 1920 or accept the pointless color-change event. I could go and and on.. To me there is already a too few events, but the important ones that were included being non-functional is a sign of poor quality control. But, well designed events make it possible to accomplish things that actually happened that are otherwise doomed to failure with this game engine.
